Energy

• Another observable characteristic of a chemical reaction is a change in energy. Some reactions absorb energy, while others release it.

A chemical reaction that absorbs energy is called an _________ reaction. This causes the combined substances to become cooler.

A chemical reaction that releases energy is called an __________ reaction. This causes the combined substances to become warmer.

endothermic
