Endothermic vs Exothermic

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 reaction.

Back

Melting ice is an example of an endothermic reaction, as it absorbs heat from the environment.

Front

Give an example of an exothermic reaction.

Back

Combustion of fire is an example of an exothermic reaction, as it releases heat and light.

Front

What happens to temperature during an endothermic reaction?

Back

The temperature decreases during an endothermic reaction because heat is absorbed.

Front

What happens to temperature during an exothermic reaction?

Back

The temperature increases during an exothermic reaction because heat is released.

Front

What is the role of heat in an endothermic reaction?

Back

In an endothermic reaction, heat is absorbed from the surroundings to facilitate the reaction.

Front

What is the role of heat in an exothermic reaction?

Back

In an exothermic reaction, heat is released into the surroundings as a product of the reaction.

Front

Are photosynthesis and respiration endothermic or exothermic processes?

Back

Photosynthesis is an endothermic process as it absorbs sunlight, while respiration is an exothermic process as it releases energy.

Front

What is the difference between endothermic and exothermic reactions in terms of energy?

Back

Endothermic reactions require energy input, while exothermic reactions release energy.
