Science CH 14

Changes of State

What is a solid? A form of matter that has definite shape and volume.
What is a liquid? A form of matter that has no definite shape but has definite volume.
What is a gas? A form of matter that has no definite shape or volume.
What is the changing from a liquid to a gas? Vaporization
What is the change from a gas to a liquid? Condensation
What is the change from a solid to a liquid? Melting
Explain what evaporation is and how it works. It is slow or gradual vaporization. It takes place at the surface of a liquid. The higher the temperature, the faster the evaporation.
Give two examples of how thermal expansion or contraction happens. Thermal expansion-When it is heated, the solid will expand or increase in size. Contraction- When the solid is cooled the particles vibrate slowly which causes it to decrease in size.
How can matter skip a state of matter and go from a solid to a gas OR a gas to a solid? When you add energy to a solid, it changes directly to a gas. This is called sublimation When energy is removed from a a gas, it changes directly to a solid. This is called deposition.
