According to the kinetic theory of gases,

Answer»

the PRESSURE EXERTED by a gas is proportional to mean square velocity of the molecules
the pressure exerted by the gas is proportional to the root mean square velocity of the molecules
the root mean square velocity is inversely proportional to the temperature
the mean translational K.E. of the molecule is directly proportional to the absolute temperature

Solution :`K.E. = (1)/(2) m Nu^(2)` since `u prop sqrtT`
`:.` K.E. depends on temperature
