ELL Practice - Exothermic vs Endothermic

Front

What is an exothermic reaction?

Back

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

Front

Give an example of an exothermic reaction.

Back

Combustion of fuels, such as burning wood or fireworks.

Front

Give an example of an endothermic reaction.

Back

Photosynthesis in plants, where they absorb sunlight to convert carbon dioxide and water into glucose.

Front

What happens to temperature in an exothermic reaction?

Back

The temperature increases in the surroundings.

Front

What happens to temperature in an endothermic reaction?

Back

The temperature decreases in the surroundings.

Front

How does making ice relate to exothermic and endothermic processes?

Back

Making ice is an exothermic process because it releases heat to the surroundings as water freezes.

Front

What is the role of energy in exothermic reactions?

Back

Energy is released during the reaction, often in the form of heat or light.

Front

What is the role of energy in endothermic reactions?

Back

Energy is absorbed from the surroundings, which can lead to a drop in temperature.

Front

How can you identify an exothermic reaction in everyday life?

Back

You can identify it by feeling heat from reactions like burning candles or fireworks.
