a gas can be easily liquefied?
151187
gases can be liquified when we increase the pressure it cool the temperature. when we increase the pressure the intermolecular space will decrease and the gas will turn to liquid form. when we compress lquid too much heat is produced so this heat has to be removed so we need to cool it.

Liquefied hydrogen has been used primarily as a rocket fuel for combustion with oxygen or fluorine, and as a propellant for nuclear-powered rockets and space vehicles. (H), a colourless, odourless, tasteless, flammable gaseous substance that is the simplest member of the family of chemical elements.

Gases become more difficult to liquefy as the temperature increases because the kinetic energies of the particles that make up the gas also increase. ... The critical temperature of a substance is the temperature at and above which vapor of the substance cannot be liquefied, no matter how much pressure is applied.

LPG (propane) expands about 270 times in volume when it goes from liquid to gas. So, 1L of liquid LPG equals 270L of gaseous LPG. As there are 1000L in a cubic metre (m³), 1 L of liquid LPG expands to 0.27 m³.

Liquid is an incompressible fluid. A gaseous fluid such as air, on the other hand, can be either compressible or incompressible. Generally, for theoretical and experimental purposes, gases are assumed to be incompressible when they are moving at low speeds--under approximately 220 miles per hour.

CNG is not to be confused with liquefied petroleum gas (LPG). The main difference between these gases is that LPG is stored as a liquid, fuelled at 8-10 bar, and is heavier than air. CNG is compressed to 250 bar and is gaseous and lighter than air.

Yes. Indeed, argon can be a solid, liquid or gas, depending on temperature or pressure. ... between -189.2 C (-308.6F)and -185.7 C (302.3F)it is a liquid, and above -185.7C (302.3F)it is a gas. Note that it has a VERY narrow temperature range for being a liquid.

The mere existence of solid noble gases may come as a surprise to some readers. ... The noble gas helium, the most difficult of all the elements to liquefy and solidify, was first liquefied by the Dutch physicist Heike Kamer lingh Onnes in 1908.

LP Gas cylinders are safe when used correctly, in accordance with the manufacturer safety instructions. However, LP Gas is a highly combustible fuel and can explode if handled irresponsibly. Even if a cylinder appears empty, residue gas can be ignited by sparks caused by cutting the metal.

Like a gas, a liquid is able to flow and take the shape of a container. Most liquids resist compression, although others can be compressed. Unlike a gas, a liquid does not disperse to fill every space of a container, and maintains a fairly constant density.
