endothermic vs. exothermic

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 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

Give an example of an exothermic reaction.

Back

Combustion of fuels, such as burning wood or fireworks.

Front

Give an example of an endothermic reaction.

Back

Front

What happens to temperature during an endothermic reaction?

Back

The temperature decreases.

Front

What is the role of heat in an exothermic reaction?

Back

Heat is released as a product of the reaction.

Front

What is the role of heat in an endothermic reaction?

Back

Heat is absorbed as a reactant in the reaction.

Front

How do fireworks demonstrate an exothermic reaction?

Back

Fireworks release heat and light when they explode, indicating an exothermic process.
