1. Kinetic Theory of Matter
Matter is made up of vibrating particles
Temperature
A measure of how hot or cold a substance is
a gain or loss of energy can cause a substance to state.
HEAT
CHANGE

SOLID LIQUID:
MELTING
Heat energy is by the solid.

Melting Point –
While the substance is melting (change in state) temperature will
