Endothermic and Exothermic Assessment

Front

What is an exothermic reaction?

Back

An exothermic reaction is a chemical reaction that releases heat to its surroundings, causing the temperature of the surroundings to increase.

Front

What is an endothermic reaction?

Back

An endothermic reaction is a chemical reaction that absorbs heat from its surroundings, causing the temperature of the surroundings to decrease.

Front

What happens to temperature during an exothermic reaction?

Back

The temperature increases.

Front

What happens to temperature during an endothermic reaction?

Back

The temperature decreases.

Front

Give an example of an exothermic process.

Back

Rusting of iron is an example of an exothermic process.

Front

Give an example of an endothermic process.

Back

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

Front

True or False: In an endothermic reaction, the system releases energy.

Back

False. In an endothermic reaction, the system absorbs energy.

Front

What is the effect of touching a beaker during an endothermic reaction?

Back

The beaker would feel cold to the touch.

Front

What is the main difference between exothermic and endothermic reactions?

Back

Exothermic reactions release heat, while endothermic reactions absorb heat.

Front

What is a common characteristic of exothermic reactions?

Back

They often feel warm or hot to the touch.
