Where goes the energy?

Electricity and Magnetism Level pending

Consider the following two cases :

(1) Initially the plates of an ideal parallel plate capacitor are charged to some potential. Then the plates are shorted.

(2) Initially the plates of an ideal parallel plate capacitor are charged to some potential. Then the polarities of the plates are reversed.

What happens to the energy stored in the capacitors in the two cases?

Energy is transformed into heat in neither of the cases Energy is transformed into heat in both the cases Energy is transformed into heat in the first case only Energy is transformed into heat in the second case only
