Will all the real gas be liquefied at high pressure?

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.


How gases are liquified?

Usually by compression and then cooling the resulting concentrate.


What is the term for gaseous substances that have been chilled until they liquefy?

They are liquefied gases.


What is LPG which property of gases are used in them?

LPG is the abbreviation for Liquefied Petroleum Gas.The property used is its inflammability for use in internal combustion engines


How are gases liquefied?

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.


Why is it that vapors can be liquefied only by compression while gases can only be liquefied by first lowering the temperature before compression?

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.


What gases are liquid?

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.


What are the gases that can be used as fuels?

Methane, natural gas, liquefied petroleum gas (LPG), butane, propane, acetylene, ethylene are gases that can be used as fuels.


Which gases cannot be liquefied by increasing their pressure?

Nig, its because the pressure is what makes the gas, if there ain't no pressure, ain't no gas.


What properties apply only to gases?

no fixed volumeno fixed shapeno specific physical form (the gas could be liquefied and even solidified)Kinetic theory of gases apply to gases only.


What is the main constituent of LPG?

LPG or Liquefied Petroleum Gas consists mainly of propane (60%) and butane (40%).
