The building blocks of matter. Two or more atoms make Molecules a molecule. The amount of molecules in a defined space or volume Density The movement of energy from high to low temperature Heat Molecules in all substances are in constant motion Kinetic Theory (even solids) of Matter When you add heat to an object the molecules move Thermal faster spreading apart, making the object larger Expansion Movement of heat in a liquid or gas Convection (molecules flow with the heat) Movement of heat as an electromagnetic wave Radiation (sunlight) Movement of heat in solids Conduction The mount of matter contained in something Mass The amount of space something takes up Volume
