Matter is made up of particles that are in constant motion
The higher the temperature, the faster the particles move (more energy)
Increase in temperature increase weakens interparticle forces, causing particles to spread apart and increase in volume/size
Gases have greatest average energy while solids have smallest average energy
According to the kinetic theory, matter is made up of particles (atoms, molecules or ions) which are in constant motion because they have energy at all temperatures above zero Kelvin (absolute zero, 0K) or -2730C. This energy is in the form of kinetic energy.
