Liquids are not compressible. Gases are compressible according to the equation pv=c, this is also called Boyles law. Liquids do not obey Boyles law and are therefore not compressible. Therefore liquids have a fixed volume.
I will refer you to Boyle's law.

Gases do have a definite volume. Using the equation pV=nRT. The gas will have a specific volume for a certain pressure, number of moles and temperature. The forces between the molecules are weaker so the gases are not held as closely together . 
I'm not totally sure just check elsewhere too
