What is an endothermic reaction?

Back

An endothermic reaction is a chemical reaction that absorbs energy from its surroundings, usually in the form of heat, resulting in a temperature decrease in the environment.

Front

What is an exothermic reaction?

Back

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

Front

Give an example of an endothermic reaction.

Back

Photosynthesis is an example of an endothermic reaction, where plants absorb sunlight to convert carbon dioxide and water into glucose and oxygen.

Front

How do endothermic reactions affect their surroundings?

Back

Endothermic reactions cool their surroundings as they absorb heat.

Front

How do exothermic reactions affect their surroundings?

Back

Exothermic reactions warm their surroundings as they release heat.
