Melting
|
The process of which a solid becomes a liquid.
|
|
|
Melting Point
|
The lowest temperature at which a substance begins to melt.
|
|
|
Freezing
|
The process of which a liquid becomes a solid.
|
|
|
Freezing Point
|
The temperature at which a specific liquid becomes a solid.
|
|
|
Evaporation
|
Is a process by which a liquid becomes a gas.
|
|
|
Sublimation
|
When a solid changes directly to a gas and a gas changes directly to a solid.
|
|
|
Boiling
|
Is another process by which a liquid becomes a gas.
|
|
|
Boiling Point
|
Boiling can occur only when the liquid reaches a certain temperature.
|
|
|
Condensation
|
The process by which a gas changes its state to become a liquid.

|
States of Matter
|
Are the different forms in which matter can exist.
These are the familiar forms: -Solids -Liquids -Gases |
|
|
Solid
|
A solid is a substance with a fixed shape and a fixed volume. The particles are close together and usually form a regular pattern. Particles in a solid can vibrate but are fixed in one place. A solid is rigid.
|
|
|
Liquid
|
A liquid has a fixed volume but not a fixed shape. A liquid takes the shape of its container. The particles in a liquid are attracted to one another so close together. However, particles in a liquid are not fixed in one place, so they can move from one place to another.
|
|
|
Gas
|
A gas has a no fixed volume and no fixed shape. A gas can take both the shape and volume of their container. Gas particles are not close together and can move easily in any direction. There is much more space between gas particles than there is between a liquid or a solid. The space between gas particles can increase or decrease with changes in temperature and pressure.
