Endo and Exo Reactions

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 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

In which type of reaction is heat a product?

Back

In an exothermic reaction, heat is considered a product.

Front

In which type of reaction is heat a reactant?

Back

In an endothermic reaction, heat is considered a reactant.

Front

What is the phase change from gas to liquid called?

Back

The phase change from gas to liquid is called condensation.

Front

What is the phase change from liquid to solid called?

Back

The phase change from liquid to solid is called freezing.

Front

What is the phase change from solid to liquid called?

Back

The phase change from solid to liquid is called melting.

Front

What is the phase change from liquid to gas called?

Back

The phase change from liquid to gas is called evaporation.

Front

What type of reaction occurs during melting?

Back

Melting is an endothermic reaction because it requires heat to change from solid to liquid.

Front

What type of reaction occurs during freezing?

Back

Freezing is an exothermic reaction because it releases heat as a liquid turns into a solid.
