Particles (molecules) in a ______________________ have more energy than the other states of matter.

• gas

• solid

• liquid

Particles of a liquid

• are tightly packed together and stay in a fixed position.

• have no viscosity.

• decrease in volume with increasing temperature.

• are free to move around one another but still touch.

• speed up and move closer together

• slow down and move farther apart

• slow down and move closer together
