Since the volume of a body can be reduced by pressure, bodies are said to be compressible. This property depends upon porosity. Gases are very compressible, solids to a much less degree, and liquids are almost incompressible.

 By doubling the pressure upon a gas its volume is diminished one half, while changing the pressure upon water from 15 lb. per square inch to 30 lb. per square inch diminishes its volume only
