DensityDensity D = m v

V = m D

M = D x v

Objects with a density greater than water’s density, which is 1.00 g/mL, will sink in water, while objects with a density less than water’s will float in water.

Temperature affects density. Since matter tends to expand when heated and contract when cooled, the density decreases with increasing temperature, and increases with decreasing temperature.

Kinetic Theory of Matter and Kinetic Theory of Matter and States of MatterStates of Matter

Kinetic Theory: all matter is made up of tiny particles in constant motion. More motion among particles (increase in KE), temperature increases, and the changes in state of matter occur.

Temperature is the measure of the average kinetic energy (KE) of the particles that make up matter.
