Question

Which energy transformation occurs when you rub your hands together to warm them?
A. kinetic energy to radiant energy B. thermal energy to kinetic energy C. thermal energy to potential energy D. kinetic energy to thermal energy

Answer 1

When you rub your hands together to warm them, the energy transformation that occurs is:

**D. kinetic energy to thermal energy.**

This is because the motion of rubbing your hands (kinetic energy) generates heat (thermal energy) due to friction.
