when
temperature of a gas changes , its pressure also changes , the temperature is a
measure of the average kinetic energy of
a gas. an increase in temperature will increase the kinetic energy of the gas ,
the gas molecule will then move more randomly colliding with one another and
with wall of the container, according to
the kinetic theory of gases . the pressure will therefore raise as a
result of raise in temperature of the gas.
on the other
hand a drop in temperature of a gas , will result in decrease in the pressure
of the gas.
because the
gas lost some of its kinetic energy , the rate of collision between gas
particles and between and the wall of the containing vessels reduces and consequently the gas pressure falls.
according to
pressure law, the pressure of fixed mass
at constant volume is directly proportional to its absolute temperature;
as the temperature rises the pressure also raises and as the temperature falls it also falls.
