What does the kinetic molecular theory explain?

The temperature of 2.00 mol Ne (g) is increased from 25°C to 200°C at constant pressure. Assuming the heat capacity of Ne is 20.8 J/K·mol, calculate the change in the entropy of neon. Assume ideal gas behavior. a.+19.2 J/Kb.-7.68 J/Kc.+7.68 J/Kd.-19.
