Phases Of Matter

Phases Of Matter Vocabulary

Altitude – vertical distance, or elevation, above sea level.
Boil –
Boiling point¬ – the temperature at which boiling occurs. At sea level, the boiling point of water is 100 °C (212 °F). Water boils at lower temperatures at higher altitudes because air pressure is lower there.
Freeze – change from a liquid to a solid.
Freezing point – the temperature at which freezing occurs. At sea level, the freezing point of water is 0 °C (32 °F).
Gas – a phase in which matter has no definite shape or volume. Gas Properties - will expand to fill any container; can be compressed; molecules relatively far apart and move freely. Water Vapor – water in the gas phase
Liquid – a phase in which matter has definite volume but no definite shape.
Liquid properties - will take the shape of a container but cannot expand or be compressed; molecules in a liquid move randomly but stay close to one another.
Melt –
Melting point – the temperature at which melting occurs. At sea level, the melting point of ice is 0 °C (32 °F).
Phase – a state of matter with certain physical properties. Solid, liquid, and gas phases occur naturally on Earth. Plasma is a phase found in stars.
Solid – a phase in which matter has a definite shape and a definite volume. Solid properties - will retain the same shape and volume in any container; atoms are held in a rigid structure and cannot move freely.

Thermal Energy –
Vaporization –
