Two pieces of identical metal are being heated at different rates. The first piece is receiving 20 J of energy per minute, and the second piece is receiving 40 J of energy per minute. Which is correct about the thermal energy? (1 point)

The thermal energy of the second piece is higher because it has a higher kinetic and potential energy.

The thermal energy of the second piece is higher because it has a higher potential energy.

The thermal energy of the second piece is higher because it has a higher kinetic energy and lower potential energy.

The thermal energy of the second piece is higher because it has a higher kinetic energy.
