I have some questions on kinetic theory of gases:
kinetic theory assumes that the inter molecular force of attraction between two molecules of a gas is negligible. This assumption applies to the condition that the said gas is either at low pressure or at high temperature. This means, when the gas is at low pressure, the molecules will be far apart and therefore the IMF is negligible. Or,also when at high temperature they will be far apart and same is true.
But the following thing is not clear to me. When the temperature is high, the velocities of the molecules will be also be high and this should result in more number of collisions which will other wise increase the pressure. that is, when the temperature is high the pressure should be also high.
