Mass, volume,energy

For a given material, mass and volume are proportional to each other.
In classical physics, the mass of an object and the energy it possesses, irrespective it is kinetic energy, potential energy or thermal energy, are proportional to each other.
In modern physics, mass m and energy E are related by Einstein's famous mass-energy equivalence equation E = m.c^2, where c is the speed of light in vacuum.
