PD3 - 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.

Front

What is an exothermic reaction?

Back

An exothermic reaction is a chemical reaction that releases heat to its surroundings.

Front

Give an example of an endothermic process.

Back

An example of an endothermic process is the reaction that occurs in a cold pack.

Front

Give an example of an exothermic process.

Back

An example of an exothermic process is fireworks exploding.

Front

What happens to heat in an endothermic reaction?

Back

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

Front

What happens to heat in an exothermic reaction?

Back

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

Front

How does an endothermic reaction affect the temperature of its surroundings?

Back

An endothermic reaction causes the temperature of its surroundings to decrease, making them feel cold.

Front

How does an exothermic reaction affect the temperature of its surroundings?

Back

An exothermic reaction causes the temperature of its surroundings to increase, making them feel warm.

Front

What type of reaction occurs in a hand warmer?

Back

A hand warmer undergoes an exothermic reaction.

Front

What is the role of heat in chemical reactions?

Back

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