Question

which energy transformation occurs when you rub your hands together to warm them

a. kinetic energy to radiate energy
b. thermal energy to kinetic energy
c. kinetic energy to thermal energy
d. thermal energy to potential energy

Answer 1

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

**c. kinetic energy to thermal energy**

In this case, the motion of rubbing your hands together (kinetic energy) generates heat due to friction, which is thermal energy.
