Question

what is effect of temperature and pressure on a gas

Answer 1

more temperature may change gas into plasma
the less the temperature and more the pressure gas changes into liquid
the more the temperature less the pressure gas may change into plasma

Answer 2

Increase in temperature increases the speed in which the gas molecules move. All gases at a given temperature have the same average kinetic energy. Lighter gas molecules move faster than heavier molecules..

Increasing the pressure on a reaction involving reacting gases increases the rate of reaction...
