Endothermic and Exothermic Assessment

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 is the SI unit of energy?

Back

The SI unit of energy is the Joule (J).

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

In a chemical reaction, where is heat in an exothermic reaction found?

Back

In an exothermic reaction, heat is a product.

Front

In a chemical reaction, where is heat in an endothermic reaction found?

Back

In an endothermic reaction, heat is a reactant.

Front

Give an example of an endothermic process.

Back

Baking bread and cooking an egg are examples of endothermic processes.

Front

Give an example of an exothermic process.

Back

Burning wood or fossil fuels is an example of an exothermic process.

Front

What is the difference between endothermic and exothermic reactions?

Back

Endothermic reactions absorb heat, while exothermic reactions release heat.
