endothermic and 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

Is photosynthesis an endothermic or exothermic reaction?

Back

Photosynthesis is an endothermic reaction.

Front

What happens to temperature during an endothermic reaction?

Back

The temperature of the surroundings decreases during an endothermic reaction.

Front

What happens to temperature during an exothermic reaction?

Back

The temperature of the surroundings increases during an exothermic reaction.

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 the role of heat in an exothermic reaction?

Back

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