Endothermic and Exothermic Reaction

Front

What is an exothermic reaction?

Back

An exothermic reaction is a chemical reaction that releases heat energy to the surroundings, resulting in an increase in temperature.

Front

What is an endothermic reaction?

Back

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

Front

Give an example of an exothermic reaction.

Back

Fireworks are an example of an exothermic reaction.

Front

What happens to heat energy during an exothermic reaction?

Back

Heat energy is released during an exothermic reaction.

Front

What happens to heat energy during an endothermic reaction?

Back

Heat energy is absorbed during an endothermic reaction.

Front

What is the temperature change in an endothermic reaction?

Back

The temperature decreases in an endothermic reaction.

Front

What is the temperature change in an exothermic reaction?

Back

The temperature increases in an exothermic reaction.

Front

Is photosynthesis an exothermic or endothermic reaction?

Back

Photosynthesis is an endothermic reaction.

Front

During evaporation, what type of reaction occurs?

Back

Evaporation is an endothermic reaction because it absorbs heat to break bonds.

Front

What is the role of heat in an endothermic reaction?

Back

In an endothermic reaction, heat is a reactant that is absorbed to facilitate the reaction.
