Changes in states
This change is state occurs when the molecules in a liquid lose thermal energy.
What is freezing?
Leaving an ice cube on a table and returning later to find a puddle of water is an example of this change in state.
What is melting?
This type of energy is often referred to as heat.
This lab showed the speed of molecules in different temperatures of water.
