true
false
Freezing occurs when molecules lose kinetic energy and move closer together.
true
false
Melting occurs when molecules lose kinetic energy and move closer together.
true
false
The particles in a solid are motionless, meaning they do not move at all and they have zero kinetic energy.
True
False
The particles in a gas have more kinetic energy than the particles in a solid or liquid
