Liquefaction by cooling down (lower temperature) and compression (higher pressure)
Air can be liquified by one of two means. 1) Lower its temperature by an extreme amount. This works because by lowering the temperature, one causes its molecules to move more slowly, so when they collide with each other, they are more likely to stick together rather than bounce off each other. 2) Apply a lot of inward pressure on it. This works because applying inward pressure will push the molecules together. The only difference between a liquid and a gas is the space between the molecules and whether the molecules are bound to one another or free to roam around.
Gasses are compressed into a smaller volume and increase in temperature. By cooling the pressurized gas back to room temperature and then allowing the gas to expand the gas will cool below room temperature. This process is repeated until the gas in question is cold enough to exist in the liquid state.
No. It takes a combination of pressure and temperature to liquefy some gases. Hydrogen and helium were the last gases to be liquefied and that was with pressure and extremely low temperature.
Helium and hydrogen cannot be liquefied by increasing their pressure alone, as they exhibit low critical temperatures and require extremely low temperatures to be liquefied.
The study of liquefied air is called cryogenics. Cryogenics is the branch of physics and engineering that deals with the production and behavior of materials at very low temperatures, typically below -150 degrees Celsius. Liquefied air is often used in cryogenic applications for its ability to store and transport gases in a compact form.
Gases can be easily liquefied by increasing the pressure and lowering the temperature. This causes the gas particles to come closer together and reduces their kinetic energy, leading to the formation of a liquid.
It's a "terrestrial" planet, because it is rocky with an iron core, like planet Earth. "Terrestrial" means "Earthlike". Jovian planets are mainly made of gases and liquefied gases.

Usually by compression and then cooling the resulting concentrate.
They are liquefied gases.
LPG is the abbreviation for Liquefied Petroleum Gas.The property used is its inflammability for use in internal combustion engines
Gases are liquefied by cooling them below their critical temperature and applying enough pressure to reach their critical pressure. This process causes the gas molecules to come together and form a liquid state. This can be achieved using various methods such as compression or expansion.
The premise of the question is incorrect, so "why" is irrelevant. You appear to be making a novel distinction between "vapors" and "gases" that I have never heard before.
All gases can be caused to change state to liquids. By either cooling, compression or a combination of both, any gas can be liquefied. This change is a physical change, by the way.
Methane, natural gas, liquefied petroleum gas (LPG), butane, propane, acetylene, ethylene are gases that can be used as fuels.
Helium and hydrogen cannot be liquefied by increasing their pressure alone, as they exhibit low critical temperatures and require extremely low temperatures to be liquefied.
no fixed volumeno fixed shapeno specific physical form (the gas could be liquefied and even solidified)Kinetic theory of gases apply to gases only.
The main constituent of LPG (liquefied petroleum gas) is a mixture of propane and butane gases.
