Amplify Phase Change Review

Front

What is the behavior of molecules in a liquid?

Back

Molecules in a liquid move around each other.

Front

What phase change occurs when a solid changes to a liquid?

Back

The phase change from solid to liquid is called melting.

Front

What happens to ice when enough kinetic energy is added?

Back

Ice melts and becomes a liquid.

Front

Which substance is more likely to change to a gas: one with strong molecular attraction or one with weak molecular attraction?

Back

Substance with weak molecular attraction is more likely to change to a gas.

Front

What effect does adding kinetic energy have on the movement of molecules?

Back

Adding kinetic energy increases the freedom of movement of the molecules.

Front

What is melting?

Back

Melting is the process where a solid turns into a liquid.

Front

What is the difference between a solid and a liquid in terms of molecular movement?

Back

In a solid, molecules vibrate in place; in a liquid, they move around each other.

Front

What is the term for the change from liquid to gas?

Back

The change from liquid to gas is called evaporation.

Front

What is condensation?

Back

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

Front

What happens to molecular attraction during a phase change from solid to liquid?

Back

Molecular attraction decreases during the phase change from solid to liquid.
