Endothermic Exothermic Practice

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

What happens to particles during an exothermic reaction?

Back

Particles decrease in kinetic energy.

Front

What happens to particles during an endothermic reaction?

Back

Particles increase in kinetic energy.

Front

What is activation energy?

Back

Activation energy is the minimum amount of energy required to initiate a chemical reaction.

Front

What is vaporization energy?

Back

Vaporization energy is the energy required to convert a substance from a liquid to a gas at its boiling point.

Front

What is the role of reactants in a chemical reaction?

Back

Reactants are the starting substances that undergo a chemical change to form products.

Front

What is the role of products in a chemical reaction?

Back

Products are the substances formed as a result of a chemical reaction.

Front

How does temperature change in an endothermic reaction?

Back

The temperature of the surroundings decreases as heat is absorbed.

Front

How does temperature change in an exothermic reaction?

Back

The temperature of the surroundings increases as heat is released.
