PD4 - MRMS MP2: 2025: Exothermic/Endothermic Flashcard

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 of the surroundings.

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 of the surroundings.

Front

What happens to temperature during an endothermic reaction?

Back

The temperature of the surroundings decreases.

Front

What happens to temperature during an exothermic reaction?

Back

The temperature of the surroundings increases.

Front

Give an example of an endothermic process.

Back

Evaporation of water is an example of an endothermic process.

Front

Give an example of an exothermic process.

Back

Respiration is an example of an exothermic process.

Front

What is photosynthesis classified as, endothermic or exothermic?

Back

Photosynthesis is classified as an endothermic reaction.

Front

What is the role of heat in an endothermic reaction?

Back

Heat is absorbed from the surroundings to drive the reaction.

Front

What is the role of heat in an exothermic reaction?

Back

Heat is released into the surroundings as a product of the reaction.

Front

How can you tell if a reaction is endothermic by touching the container?

Back

If the container feels cold to the touch, the reaction is likely endothermic.
