Homework Answers
#1. On increasing temperature the kinetic energy of gas molecules increases and thus no. Of molecules having most probable velocity will increase because the increased temperature will increase the velocity of those molecules which were below the most probable velocity.
Hence option (a) is the correct answer.

There is a cylinder which contains 1 mole of ideal gas which initial pressure, volume, temperature is A, B, D. If heat(q) is injected to this cylinder, the pressure of gas changed into sqrt(2)R*A, the volume of gas changed into 2.5B, and the temperature of gas changed into 5*sqrt(R)*D. Calculate the heat in terms of A, B, D. (Molar heat capacity Cv=2R).
