A student uses a heat lamp to keep a tortoise warm during the winter months.

The turtle stays warm because the lamp _____________

• Turns electrical energy into thermal enrgy.

• Conserves energy by ionizing molecules around it.

• Causes kinetic energy to turn to potential energy.

• Decreases the molecular motion of the molecules around it.
