The solids

Kinetic theory of matter
It explains the different states of matter. Gas, solid and liquids have different amounts of energy. Matter is anything that takes up in the space if u can touch it smell it etc it is matter

Atoms
They are the smallest particles that make up the matter. They are make for a combination of two elements when the states are in solid they are together but in a gas state they are all separated

Matter in motion
Particles moving are or use kinetic energy because they are constantly moving

Temperature and heat
When particles move fast they have a higher temperature so Heat transfer of thermal energy from warmer to cooler objects
