Physical Behavior of Matter Review

Front

What is an endothermic process?

Back

An endothermic process is a reaction or change that absorbs heat from the surroundings, resulting in a decrease in temperature of the surroundings.

Front

What is an exothermic process?

Back

An exothermic process is a reaction or change that releases heat to the surroundings, resulting in an increase in temperature of the surroundings.

How does heat transfer between objects?

Back

Heat will always transfer from the hottest object to the coolest object.

Front

What is a chemical change?

Back

A chemical change is a process that results in the formation of one or more new substances with new chemical properties.

Front

What happens during vaporization?

Back

Vaporization is the process where a liquid changes into a gas.

Front

What is sublimation?

Back

Sublimation is the process where a solid changes directly into a gas without passing through the liquid state.

Front

What is condensation?

Back

Condensation is the process where a gas changes into a liquid.

Front

What is freezing?

Back

Freezing is the process where a liquid changes into a solid.

Front

What is the difference between a physical change and a chemical change?

Back

A physical change does not create a new substance, while a chemical change results in the formation of new substances.

Front

What is a phase change?

Back

A phase change is a transition of matter from one state (solid, liquid, gas) to another.
