Case-I : The temperature of the walls of a vessel containing a gas at temperature T, is `T _("wall").` it is known that ` T_("wall") gt T.-`
Case-II : same gas fill in an another vessel has temperature `T _("wall") lt T` (All other conditions are keeping same), Then

A

Pressure exerted by gas on wall is higher in case I than in case II

B

Average kinetic energy of gas molecules after collision is higher in case I than in case II

C
