Answer: option C. Increase the pressure on a gas decreases the volume.Explanation:the Compressibility is the material property that relates the change (decrease) of volume under pressure (compression).Is defined as the relative change in volume in comparison with a change in pressure.The Gases in normal conditions of pressure and temperature are highly compressible, since the molecules are far apart.You can see the inverse relationship between pressure and volume in a gas by looking at the ideal gas equation:pV = nRTHence, constant n, R, and T means pV = constant, as well as p V increases decreases, which leads to the conclusion option C: the increase of the pressure on a gas decreases the volume.
