Question

If a gas is allowed to expand at constant tempeature then which of the following does not hold true :

Options

A.the kinetic energy of the gas molecules decreases
B.the kinetic energy of the gas molecules increases
C.the kinetic energy of the gas molecules remains the same
D.Can not be predicted
