states of matter

• Everything contains matter.
• Matter is any substance that has mass and takes up space, meaning it is influenced by gravity and has a weight.
• Matter can be described using shape, colour, density, melting point, strength, fragility, elasticity, and conductivity.
• All matter is made of tiny particles called atoms and molecules, which are always moving.
• Pressure and temperature control how fast the particles move.
• The movement of the particles determines the state of the matter.
• Matter can exist in three different states: solid, liquid, and gas.
