Question

Do changes in temperature and pressure affect gas behavior? If so, how?

Answer 1

When the temperature of a gas is decreased, gas converts into liquid state but when a high pressure is applied on a gas , it also converts into liquid state.

Explanation:

If we lower the temperature of a gas, the particles of the gas loose all the kinetic energy and become less movable. Due to this all the particles of the gas come more close to each other and get condense on any solid surfaces and becomes liquid.

For example, water vapours get condense on the surface of a cold drink bottle when these water vapours get in contact with the cool surface of the bottle.

If we apply the high pressure on a gas, all the particles come very close to each other and become dense and changes into liquid.
