What is the definition of thermochemistry?
The branch of chemistry concerned with the quantities of heat evolved or absorbed during chemical reactions.
Chemical reactions which release energy from the chemicals into the surroundings.
What is the definition of a product?
A substance that is formed as a result of a chemical reaction.
No, it releases it.

Thermal energy
What is the definition of thermal (heat) energy?
The energy contained within a system that is responsible for its temperature.
Any chemical reaction that absorbs heat from its environment.
The starting materials in a reaction that undergo a chemical change to form a product.
Does endothermic reaction take in energy?
Yes, it takes in energy.
What one is energy that travels through space as electromagnetic waves.
Radiant energy.
What is the definition of radiant (light) energy?
Energy that is transferred by electromagnetic radiation, such as light, X-rays, gamma rays, and thermal radiation.
