PD1- MRMS MP2: 2025: Exothermic/Endothermic Flashcard

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

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

Give an example of an exothermic process.

Back

Fireworks exploding is an example of an exothermic process.

Front

Give an example of an endothermic process.

Back

Baking cupcakes is an example of an endothermic process because the oven temperature decreases.

Front

What happens to temperature in an exothermic reaction?

Back

In an exothermic reaction, the temperature increases.

Front

What happens to temperature in an endothermic reaction?

Back

In an endothermic reaction, the temperature decreases.

Front

Is respiration an exothermic or endothermic reaction?

Back

Respiration is an exothermic reaction.

Front

In an endothermic reaction, heat is...

Back

In an endothermic reaction, heat is taken in or absorbed.

Front

In an exothermic reaction, heat is...

Back

In an exothermic reaction, heat is given out or released.

Front

What is the role of heat in chemical reactions?

Back

Heat can either be absorbed or released during chemical reactions, determining if the reaction is endothermic or exothermic.
