    if Planck's constant were zero, then the system behaved as a classical system and the energy is KT.....

    i agree with rubiii case of black body radiation it would be infinite and in case of monoatomic gas it would be 3kT/2

    also note that in classical case, energy is continuous while in quantum case energy is discrete.... remember these two regards...

    dear you know Planck constant zero means it's classical because h is not introduced in classical ,there all quantum results will fail if h is zero ..

    plank constant zero means no quantum results only classical results will appear. so the energy will be classical.
