Explaining Patterns in Melting
Substances change their state at different temperatures.
The substances in the graph change from solids to liquids with different amounts of energy (heat).

Phase In, Phase Out
Changing the state of matter is an example of a physical change.
This is also called phase change.
It means that going from solid to liquid to gas and back again does not change the matter present.
9
Phase In, Phase Out
Imagine a teakettle filled with water. The kettle is heating up. What is happening to the water inside?
The water is a liquid. When it reaches its boiling point, it will turn into a gas.
10
Phase In, Phase Out
As the gas tries to escape from the kettle, it whistles (remember that gas particles move very fast)
After teh kettle is removed from the heat, it will start to cool.
This changes the gas back into a liquid.
