The three states of matter are solids, liquids and gas'.
Matter is anything that has mass and takes up space.
Mass = how much matter is in an object. (Measured with a balance). Unit for measurment: grams (g) and kiliograms (kg).
PROPERTIES OF THE STATES OF MATTER
SOLID: has a definite shape and volume but can not compress and particles cannot flow.
LIQUID: particles CAN flow and does not have a definite shape ( liquids take the shape of the container that they are poured into). Cannot compress and does have a definite volume.
GAS: can flow and compress. Does not have a definite shape or volume.
Enclosed is a helpful/educational video on our current concept:
REVISION SO FAR:
Solid, liquid and gas.
Solids can't compress or flow and do have definite shapes and volumes.
Liquids can flow and have definite volumes. They do not have definite shapes and CAN'T be compressed.
Gas's can flow and have a definite volume. They can't compress and don't have a definite shape.
MATTER: Anything that has space and mass.
MASS: How much matter an object takes up.
Change of state
SOLID (melt) LIQUID (boil) GAS (melt) LIQUID (freeze) SOLID.
DIFFUSION: The flow of particles from an area of high concentration to an area of low concentration.
