a.) compressibility is a measure of the relative volume change of a fluid or solid as a response to a pressure change. In its simple form, the compressibility β may be expressed as , where V is volume and p is pressure.

b.) Diffusion is the net movement of anything from a region of higher concentration to a region of lower concentration.

c.) Pressure (symbol: p or P) is the force applied perpendicular to the surface of an object per unit area over which that force is distributed.

d.) The density, of a substance is its mass per unit volume. The symbol most often used for density is ρ, although the Latin letter D can also be used. Mathematically, density is defined as mass divided by volume: where ρ is the density, m is the mass, and V is the volume.
