Exothermic vs Endothermic

Front

What is an exothermic reaction?

Back

An exothermic reaction is a chemical reaction that releases energy in the form of heat, causing the temperature of the surroundings to increase.

Front

What is an endothermic reaction?

Back

An endothermic reaction is a chemical reaction that absorbs energy from its surroundings, resulting in a decrease in temperature.

Front

What happens to temperature during an endothermic reaction?

Back

The temperature decreases outside of the reaction.

Front

What happens during the condensation of water vapor?

Back

It is an exothermic process where water vapor releases heat and turns into liquid water.

Front

What is the result of adding acid to water?

Back

It is an exothermic reaction that can produce heat and may cause an explosion.

Front

What is the process of making ice classified as?

Back

Making ice is an exothermic process because it releases heat to the surroundings.

Front

What is evidence of a chemical reaction?

Back

When two substances react, they form a new substance.

Front

Give an example of an exothermic reaction.

Back

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

Front

Give an example of an endothermic reaction.

Back

Photosynthesis in plants is an endothermic reaction that absorbs sunlight.

Front

What is the role of energy in exothermic reactions?

Back

Energy is released to the surroundings, increasing the temperature.
