Why must the effort applied to a pulley system be applied over a distance of 6.00 meters to raise the load 1 meter. It could be a liquid or it could still be a gas depending on the type of gas and the temperature. Is the buoyant force on her the same in both cases? ? What would happen if you set an ice cube on fire? ? It didn't say anything about temperature, type of fluid, etc. This is why you can pour, but not compress, a liquid. Why can you get LP gas in a tank but not natural gas? 2 Liquid Oxygen Oxygen, like most other elements, can exist in three forms: liquid, solid or gaseous. If you increase the pressure enough, the gas becomes a liquid (this is, in fact, one common way to produce liquid gases, like liquid natural gas and liquid nitrogen). Joule-Thomson effect is used for the liquefaction of air. This will release even more heat than just compressing the gas because the gaseous state of a substance has more energy than the liquid state. I got 1.5 points out of 2 for that. Can anyone help me with calculating the first excitation energy of a proton ? Solid. What is the reality of working as a physicist? In fact reducing the pressure for things that are liquid at Earths atmospheric pressure will … However, it requires a great deal of pressure to accomplish a little compression. However, gasifiers used to collect and condense wood gas for immediate use may prove valuable as a future alternative fuel source. Right now, you are probably sitting on a chair, using a mouse or a keyboard that is resting on … In comparison to other fuels, natural gas poses less of a threat in the event of a spill, because it is lighter than air and disperses quickly when released. One common use of compressed gas is in scuba diving tanks, where oxygen is compressed to the point that 600 liters can fit into a three liter tank. You can also turn oxygen from a gas into a liquid by reducing the temperature. Use particle theory to explain. But for the most common temperatures, it will become a liquid. Air, being a mixture of gases can also be converted into liquid state. When you compress a gas, the atoms or molecules get closer together and bang into each other more frequently. You can't compress a liquid as much simply because there isn't as much space between particles. Gases can be compressed because each gas particle has relatively vast amounts of room between it and all other gas particles the majority of the time. Soda bottles can hold around 90PSI of pressure before exploding. If you compress a gas enough then it will undergo a phase change and turn to liquid. So that the condensation occurs. Hydrogen is the most abundant element in the universe. A supercritical fluid (SCF) is any substance at a temperature and pressure above its critical point, where distinct liquid and gas phases do not exist, but below the pressure required to compress it into a solid. I don't know if it's exactly 90PSI so I only go for around 40PSI max for me. There is no chemical change,only physical change.But Carbon di oxide (a gas) after compression becomes a solid which is popularly called "Solid Ice". Another Answer: As you start to compress the gas you will get an increase in pressure. can you help me ? It's not impossible. This equation shows … Scientists take an important step in converting methane gas to a liquid, giving the potential of making it more useful as a fuel and as a source for making other chemicals. This demonstration uses some common objects to illustrate a simple, but important point. As you start to compress the gas you will get an increase in pressure.As the pressure increases you will hit a point where you will start to condense liquid from the gas. However, propane has the nice property that when you compress it, it condenses into a liquid and will stay that way until it is uncompressed. You must also make the molecules closer so that it is a phase change from a gas to liquid . I have methane gas coming from MSW landfill , and I compress become a liquid , how I have to do it ? The composition of wood gas and the necessary fuel-to-air combustion ratio make storing wood gas uneconomical. … If it was compressed to the liquid state, you'd call itliquified natural gas (LNG). no it's a gas, compressed to around 1% of normal volume. To understand what happens, remember that all matter is composed of a collection of atoms. Unfortunately, liquefying hydrogen isn't as easy as turning steam i… If you increase the pressure you force the atoms closer together until they condense (reverse boil) into a liquid. (assuming heat generated is removed)As the pressure continues to increase the amount of gas present decreases and the amount of liquid increases.You will eventually reach a point where there is no gas present, only liquid. Who's right? When your hydrogen tank fills, open the tank a hair to let the gas in. I just thought up a way to compress the hydro-oxy gas mix I'm gonna get from my future electrolysis tank. But for the most common temperatures, it will become a liquid. Firstly, we need to identify that the state of matter of air is gas. Air from the atmosphere is compressed to a high … Wood gas can be compressed and stored in a tank. This contrasts with liquids and solids, which have particles in constant contact with one another, and thus little room to compress. Still have questions? Describe what happens when a gas is strongly compressed in a strong, sealed container? Then you cool off the compressed gas and let it expand. Get answers by asking now. As the pressure increases you will hit a point where you will start to condense liquid from the gas. Under normal atmospheric pressure, air has to be cooled to (-) 200 degree-centigrade and under high pressure to (-) 141 degree-centigrade to convert into liquid. As the pressure increases you will hit a point where you will start to condense liquid from the gas. What do you get when you play every musical note all at once at the same time? In summary. In general, it’s defined as how much a liquid or a solid can resist the pressure applied to compress it from all the directions. What do you think of the answers? Gases can be cooled and compressed into a smaller volume of liquid. Posted 5 years ago As you start to compress the gas you will get an increase in pressure. CNG combustion produces fewer undesirable gases than the aforementioned fuels. If it's pure hydrogen and not hho gas you can't compress it using standard at home equipment but you can store it as a useable gas in a tank no problem. I can’t compress liquid but i can turn eight pints of ale into eleven pints of piss.So it seems you can expand a liquid even if you can’t compress it. For helium, you take the gas and compress it. A gas can be converted into a liquid by increasing the pressure & decreasing temperature. For example steam has a triple point at around 700 F. No matter how hard you compress it, if the temperature is above the triple point, it will still be steam, not water. P.S., It was after she reworded for second time cause we "misunderstood". (assuming heat generated is removed). That's it. However, when it comes to the task of storing hydrogen for use, there is a hurdle to clear: Hydrogen exists as a gas by default but is most useful when stored as a liquid. As the pressure increases you will hit a point where you will start to condense liquid from the gas. Composed of one proton and one electron, it is the lightest element known to mankind and due to its ability to carry energy along with its abundance on Earth, hydrogen may be the key to a cleaner, more efficient power supply. If you compress your gas enough (and lower the temperature), eventually the particles will come close enough that they start to attract each other, and then your gas turns into a liquid. For that reason, liquids and solids are sometimes referred to as being incompressible. Under normal circumstances, you will encounter gaseous oxygen. Methane is considered to be non-compressible in gas form because when it is compressed, it reverts to liquid form, which is why oil refineries burn off their excess methane gas … why does measuring a particle make its wavefunction collapse? This can be explained by the ideal gas law, V = nR(T/P), where V is volume, nR, for this discussion, is a combined constant, T is temperature, and P is pressure. Liquefied natural gas (LNG) is natural gas (predominantly methane, CH 4, with some mixture of ethane, C 2 H 6) that has been cooled down to liquid form for ease and safety of non-pressurized storage or transport.It takes up about 1/600th the volume of natural gas in the gaseous state (at standard conditions for temperature and pressure).It is odorless, colorless, non-toxic and non-corrosive. In this state, with a temperature approaching near absolute zero, the methane gas would turn into liquid methane. Negative pressure the tank with a vacuum pump to -30lbs. So that the condensation occurs. In a liquid the particles still touch their neighbours but they move around, sliding over each other. As you start to compress the gas you will get an increase in pressure. When gas is compressed, the particles are forced much closer together, allowing a huge amount of particles to fit in a small space. Yes you can, water may push apart when it gets colder, but you can over come that with more pressure. The answer is yes, You can compress water, or almost any material. Propane normally changes from a liquid to a gas at -46 F (-43 C). Thus, compression, which is essentially forcing the gas particles closer together, has a great deal of space to reduce. Look up something called the ideal gas law. You can sign in to give your opinion on the answer. It can effuse through porous solids like a gas, overcoming the mass transfer limitations that slow liquid transport through such materials. One property of gas is that it has no definite volume and can be compressed. Then hook it to your hydrogen tank from your generator. This is a word-for-word from my science quiz (got 9.5 out of 10). Compressed natural gas is a fuel that can be used in place of petrol (gasoline), diesel fuel, and liquefied petroleum gas (LPG). You will eventually reach a point where there is no gas present, only liquid. Consider a swimmer who swims first in a freshwater lake, and then swims in the ocean. … With gasses this is even nicely predictable over a wide range. Hence, even when the mattress is fully inflated, air can still be pumped into the mattress as there are “empty spaces” between the air particles, just like in the aforementioned Scenario #2. It could be a liquid or it could still be a gas depending on the type of gas and the temperature.For example steam has a triple point at around 700 F. No matter how hard you compress it, if the temperature is above the triple point, it will still be steam, not water. Will compressing a gas turn it into a liquid. In the same way as you can fill a bicycle tire with more air by adding pressure, you can compress oxygen with any pressure your container will hold. In short, I said that the gas would RESEMBLE a liquid, but still be a gas. Liquid? This means that methane has to be cooled to a much lower temperature than propane in order to be turned to a liquid that can be stored in a tank. As the pressure continues to increase the amount of gas present decreases and the amount of liquid increases. Propane molecules consist of three carbon atoms bonded in a chain with eight hydrogen atoms bonded to these carbon atoms. But before you could throw in a debatable statement of incompressible fluids into our discussion box below, you might have to brush up about the term bulk modulus. Teacher said it becomes a liquid. You just keep doing this over and over until you get the stuff cold enough. Join Yahoo Answers and get 100 points today. As per this effect, expansion into vacuum cools the air. The attractive forces between the particles in a gas are very weak, so the particles are free to move in any direction.
