Question

1. what type of energy is being described or used? thermal/heat chemical mechanical electrical light/radiant

Explanation:

When a candle burns, it undergoes a chemical reaction (combustion). The wax (a chemical substance) reacts with oxygen. During this reaction, chemical energy stored in the wax is released. Part of this energy is given off as heat (thermal energy) and part as light (radiant energy). So, the main energy type related to the reaction (as the source) is chemical energy.

Answer:

chemical
