Endothermic and Exothermic Reactions-Levings

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

Give an example of an endothermic process.

Back

Baking bread is an example of an endothermic process because it requires heat to cook.

Front

Give an example of an exothermic process.

Back

Burning wood is an example of an exothermic process because it releases heat.

Front

What happens to temperature during an endothermic reaction?

Back

The temperature decreases because heat is absorbed from the surroundings.

Front

What happens to temperature during an exothermic reaction?

Back

The temperature increases because heat is released into the surroundings.

Front

What instrument is commonly used to measure temperature changes in reactions?

Back

A thermometer is used to detect temperature changes in endothermic and exothermic reactions.

Front

How do endothermic reactions feel to the touch?

Back

Endothermic reactions feel cold to the touch because they absorb heat.

Front

How do exothermic reactions feel to the touch?

Back

Exothermic reactions feel hot to the touch because they release heat.

Front

What is the law of conservation of energy in relation to chemical reactions?

Back

The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another during chemical reactions.
