Endothermic/Exothermic Reactions

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 immediate environment to increase.

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 the temperature of the immediate environment.

Front

Give an example of an exothermic reaction.

Back

Combustion of fuels, such as burning wood or gasoline, is an example of an exothermic reaction.

Front

Give an example of an endothermic reaction.

Back

Photosynthesis in plants is an example of an endothermic reaction, as it absorbs sunlight to convert carbon dioxide and water into glucose.

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

What is the role of heat in an endothermic reaction?

Back

In an endothermic reaction, heat is taken in from the surroundings.

Front

What is the role of heat in an exothermic reaction?

Back

In an exothermic reaction, heat is given out to the surroundings.

Front

What is rusting in terms of chemical reactions?

Back

Rusting is an exothermic reaction where iron reacts with oxygen and moisture, releasing heat.

Front

What is the difference between endothermic and exothermic reactions?

Back

Endothermic reactions absorb heat, while exothermic reactions release heat.
