Amplify Phase Change Chapter 2 and 3

Front

What happens to kinetic energy when a gas changes phase to a liquid?

Back

Kinetic energy is removed.

Front

Why does only water vapor condense to a liquid when it contacts a cold soda can, but not nitrogen gas?

Back

The cold soda can didn't take away enough kinetic energy for the phase change to occur.

Front

What happens to the movement of water molecules when energy is removed and water changes phase from liquid to solid?

Back

The water molecules move slower and started moving in place.

Front

In which state of matter do the molecules move in place?

Back

Solid.

Front

What is the phase change called when a liquid turns into a solid?

Back

Freezing.

Front

What is the phase change called when a solid turns into a liquid?

Back

Melting.

Front

What is condensation?

Back

The process where a gas turns into a liquid.

Front

What is evaporation?

Back

The process where a liquid turns into a gas.

Front

What happens to the kinetic energy of molecules during freezing?

Back

Kinetic energy is removed.

Front

What is the state of matter where molecules are far apart and move freely?

Back

Gas.
