There are 3 basic states of matter : solid, liquid and gas..
SOLID
- A solid is anything that holds a particular size and shape.
- An apple, a block of wood, and a penny are all solids.
- The only way they can change their shape is by force.
- The particles in a solid are tightly packed and don't make a lot of movements.
- There is not much free space in between the particles, so there is very little room for the particles to move.
- Solid have mass.
LIQUID
- A liquid is anything that has size or volume, but does not have a shape.
- Liquids must be contained in a cup, bottle or receptacle in order to have a shape.
- Milk, water and juice are liquids.
- Liquids particles are not so close together as particles of solid.
- They move around and past each other much more freely.
- They have no regular shape or arrangement and move freely.
- Liquid have mass.
GAS
- Gases are hard to identify because they have no colour or shape.
- It has no shape or size.
- Take a deep breath and feel your lungs get bigger, your lungs are filling up with air, and air is a combination of many gases.
- The particles in a gas move freely at high speeds.
- There is a lot of free space in between the particles, and they take shape of any container.
- Gases have mass.
