Q2 Test 3

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 temperature in an endothermic reaction?

Back

The temperature decreases because heat is absorbed from the surroundings.

Front

What happens to temperature in an exothermic reaction?

Back

The temperature increases because heat is released to the surroundings.

Front

Give an example of an exothermic reaction.

Back

Dynamite exploding 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 is the main characteristic of exothermic reactions?

Back

Exothermic reactions are characterized by the release of heat.

Front

What is the main characteristic of endothermic reactions?

Back

Endothermic reactions are characterized by the absorption of heat.

Front

How do you identify an exothermic reaction?

Back

An exothermic reaction can be identified by a rise in temperature during the reaction.

Front

How do you identify an endothermic reaction?

Back

An endothermic reaction can be identified by a drop in temperature during the reaction.
