The Coefficient of Compression is the decrease in length per unit change in temperature of a solid, liquid, or gas at a constant pressure.

The Coefficient of Expansion is the change in length per unit change in temperature of a solid, liquid, or gas at a constant pressure.

The Coefficient of Friction is a value that shows the relationship between the force of friction between two objects and the normal reaction between the objects that are involved.
