Endothermic and Exothermic reactions

Front

What is an Exothermic reaction?

Back

An Exothermic reaction is a chemical reaction that releases 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 heat, causing the temperature of the surroundings to decrease.

Front

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

Give an example of an Endothermic reaction.

Back

Photosynthesis in plants is an example of an Endothermic reaction.

Front

What happens to temperature during an Exothermic reaction?

Back

The temperature increases during an Exothermic reaction.

Front

What happens to temperature during an Endothermic reaction?

Back

The temperature decreases during an Endothermic reaction.

Front

Is cooking bacon an Exothermic or Endothermic reaction?

Back

Cooking bacon is an example of an Endothermic reaction.

Front

What is the role of heat in an Exothermic reaction?

Back

In an Exothermic reaction, heat is released into the surroundings.

Front

What is the role of heat in an Endothermic reaction?

Back

In an Endothermic reaction, heat is absorbed from the surroundings.

Front

What is a common characteristic of Exothermic reactions?

Back

Exothermic reactions often produce light or sound, in addition to heat.
