Question 3 • Physics I

Which energy transformations occur when a candle burns?

Answer
A
Thermal energy transforms into radiant energy and chemical energy.
B
Chemical energy transforms into thermal energy and radiant energy.
C
Chemical energy transforms into thermal energy and electrical energy.
D
Thermal energy transforms into mechanical energy and radiant energy.

Explanation

The wax in a candle stores chemical energy. When it burns, that chemical energy is released mainly as thermal energy (heat) and radiant energy (light), so the correct choice is B: chemical energy transforms into thermal energy and radiant energy.
