Forms of Matter

Solid solid

- has definite shape and size.

- their molecules are packed very close to each other

- Solids also can hold their own shape.

 

 

Liquidliquid

- liquid do not have definite shape but have definite size.

- liquid follow the shape of the container.

- the molecules of liquids are farther apart than in solids so they can move more freely.

- liquids are fluid because they can flow.

 

 

Gas

- can be squeezed into containers like balloons, gas

   but if they are released, they spread into a    wider space.

- the molecules of gases are very far apart.

- gases do not have definite shapes and sizes because

   they are free to spread out at all directions.

 

 

 

Phases of matter also change into different forms.

 

Physical change is a change in the form of matter but not in its identity.

Examples:

dissolving sugar into water

ice melting to water

 

Chemical change is a change in which one kind of matter is changed into a different type of matter.

Examples:

the rusting of your car

setting your shoe on fire

digesting food

    Liquids have no definite shape but has a definite volume not size. Gases have no definite shape nor volume not size. Another phase is plasma which is gas heated to a very high temperature causing electrons to separate from its atom. Plasmas conduct electricity.

    Gases cannot be squeezed into its containers since it expands to fill its container and doesn’t contract to it
