Endothermic & Exothermic Reactions

Front

What is an endothermic reaction?

Back

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

Front

What is an exothermic reaction?

Back

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

Front

What happens to energy in an exothermic reaction?

Back

Energy is released during an exothermic reaction.

Front

What happens to energy in an endothermic reaction?

Back

Energy is absorbed during an endothermic reaction.

Front

Is photosynthesis an endothermic or exothermic reaction?

Back

Photosynthesis is an endothermic reaction.

Front

What is an example of an exothermic reaction?

Back

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

Front

What is an example of an endothermic process?

Back

Baking bread and cooking an egg are examples of endothermic processes.

Front

How can you tell if a reaction is endothermic based on temperature change?

Back

If the temperature decreases during a reaction, it is likely an endothermic reaction.

Front

How can you tell if a reaction is exothermic based on temperature change?

Back

If the temperature increases during a reaction, it is likely an exothermic reaction.

Front

What is the role of heat in an endothermic reaction?

Back

In an endothermic reaction, heat is taken in from the surroundings.
