# Volume

Written by Jerry Ratzlaff on . Posted in Thermodynamics

Volume, abbreviated as V, is the space occupied by a mass.  Volume is a extensive variable whose values depend on the quantity of substance under study.  It is expressed in terms of length cubed, a quantity of three dimensional space occupied by gas, liquid, or solid.  Volume is a scalar quantity having direction, some of these include area, density, energy, entropy, length, mass, power, pressure, speed, temperature, and work.

## Formulas that use volume

 $$\large{ V = l \; w \; h }$$ $$\large{ V = \frac{ m }{ \rho } }$$ $$\large{ V = \frac {n \; R \; T}{p} }$$ (ideal gas law)

### Where:

$$\large{ V }$$ = volume

$$\large{ \rho }$$   (Greek symbol rho) = density

$$\large{ h }$$ = height

$$\large{ l }$$ = length

$$\large{ n }$$ = number of moles of gas

$$\large{ m }$$ = mass

$$\large{ n }$$ = mole

$$\large{ p }$$ = pressure

$$\large{ R }$$ = specific gas constant (gas constant)

$$\large{ T }$$ = temperature

$$\large{ w }$$ = width
