Endothermic and Exothermic Reactions

Front

What is an exothermic reaction?

Back

An exothermic reaction is a chemical reaction that releases heat to its surroundings.

Front

What is an endothermic reaction?

Back

An endothermic reaction is a chemical reaction that absorbs heat from its surroundings.

Front

Give an example of an exothermic reaction.

Back

An example of an exothermic reaction is the freezing of water into ice.

Front

What happens to temperature during an exothermic reaction?

Back

The temperature of the surroundings increases during an exothermic reaction.

Front

What happens to temperature during an endothermic reaction?

Back

The temperature of the surroundings decreases during an endothermic reaction.

Front

What is the main characteristic of endothermic processes?

Back

Endothermic processes require an input of energy, usually in the form of heat.

Front

What is the significance of heat in exothermic reactions?

Back

In exothermic reactions, heat is released, which can be harnessed for various applications.

Front

What is a common example of an endothermic process in cooking?

Back

Baking bread is a common example of an endothermic process.

Front

What is the role of heat in the rusting of iron?

Back

In the rusting of iron, heat is released, making it an exothermic process.
