Choose the only correct statement from the following 

a
The pressure of a gas is equal to the total kinetic energy of the molecules in a unit volume of the gas
b
The product of pressure and volume of gas is always constant
c
The average kinetic energy of molecules of a gas is proportional to its absolute temperature
d
The average kinetic energy of molecules of a gas is proportional to the square root of its absolute temperature

detailed solution
