Cards (13)

Endothermic reactions absorb energy from their surroundings.
Exothermic reactions are often used to generate heat, such as burning fuels or combustion reactions.
The reaction is exothermic as it releases energy (heat) into its surroundings.
Exothermic reactions release energy into their surroundings.
