How do you show that a force can change the volume of an object?

Answer:
Suppose there's an object of certain density, then we know that :
Density = Mass / Volume
Since mass is a constant quantity ( cannot be changed by any process except mass energy convergence in nuclear radiation ),
Density is inversely proportional to volume.
Now there's a term called compressibility factor or just compressibility. ( It is inverse of Bulk modulus ) ….force applied over a body can compress a body which would change it’s density, increase it's density which means decrease it's volume as they are inversely proportional.
Conversely it can be said if density will decrease then volume will increase.So the volume cannot be changed as long as density is constant, whatever the process.
Eg. Density of solid is higher than liquid and liquid has higher than gas which would lead to a conclusion that solid will have lower volume than liquid and liquid has lower volume than gas at constant mass.
