Physical Properties Boiling Point – the temperature at which a substance turns from a liquid to a gas

Physical Properties Boiling Point When a liquid becomes a gas it is called boiling

Physical Properties Boiling Point When a liquid becomes a gas it is called boiling or vaporization. What happens? At a certain temperature called the boiling point, the molecules will gain enough energy to break free and become a gas.

Physical Properties Melting Point – the temperature at which a substance turns from a solid into a liquid

The temperature at which a solid turns into a liquid is called the melting

The temperature at which a solid turns into a liquid is called the melting point. Physical Properties As the energy in the molecules increases from a rise in temperature, the molecules start moving faster. Eventually, they have enough energy to break free of their rigid structure and start moving around more easily and the matter becomes a liquid. The melting point for water is 0 degrees C (32 degrees F).

Physical Properties Freezing Point – the temperature at which a substance turns from a liquid to a solid

The temperature at which a liquid turns into a solid is called the freezing

The temperature at which a liquid turns into a solid is called the freezing point. Physical Properties As the energy in the molecules decreases from a fall in temperature, the molecules start moving slower. Eventually, they don’t have enough energy to move easily and they are confined to a rigid structure. The matter becomes a solid. The freezing point for water is 0 degrees C (32 degrees F).
