Question

2.1.4 quiz: conservation of energy
question 6 of 10
when sunlight strikes the side of a building, what form of energy is it transformed to?

a. kinetic energy
b. gravitational potential energy
c. chemical energy
d. thermal energy

Explanation:

Sunlight is electromagnetic energy. When it strikes a building, the building absorbs the energy and its temperature increases, which is thermal energy. Kinetic energy is related to motion, gravitational potential energy to height and mass, and chemical energy to chemical bonds—none of these match the energy transformation here.

Answer:

D. Thermal energy
