Endothermic and Exothermic Reactions

Front

What is an exothermic reaction?

Back

An exothermic reaction is a chemical reaction that releases heat to its surroundings.

Front

What happens to the temperature during an exothermic reaction?

Back

The temperature increases during an exothermic reaction.

Front

What is an endothermic reaction?

Back

An endothermic reaction is a chemical reaction that absorbs heat from its surroundings.

Front

What happens to the temperature during an endothermic reaction?

Back

The temperature decreases during an endothermic reaction.

Front

Can you give an example of an exothermic reaction?

Back

Combustion of fuels, such as burning wood or gasoline, is an example of an exothermic reaction.

Front

Can you give an example of an endothermic reaction?

Back

Photosynthesis in plants is an example of an endothermic reaction.

Front

What is the role of heat in exothermic reactions?

Back

In exothermic reactions, heat is released as a product of the reaction.

Front

What is the role of heat in endothermic reactions?

Back

In endothermic reactions, heat is absorbed as a reactant in the reaction.

Front

How do hand warmers work in terms of chemical reactions?

Back

Hand warmers typically use exothermic reactions to generate heat, warming the surrounding area.

Front

What is the effect of an endothermic reaction on its surroundings?

Back

An endothermic reaction makes its surroundings feel cold due to the absorption of heat.
