Ideal Gas Law - Definition

Ideal Gas Law also known as Universal Gas Law denotes the relationship between properties of an ideal gas. Ideal Gas Law in general combines Boyle's Law, Charles Law, Gay Lussac's Law and Avagadro's Law into one.


Ideal Gas Law Equation

Ideal Gas Law Equation states that pressure multiplied by volume is equal to product of number of moles with universal gas constant and temperature. The Ideal Gas Formula is given by PV = nRT

  • Where, P = pressure
  • V = volume
  • n = number of moles
  • T = temperature
  • R = gas constant

We can rearrange the above equation to determine each parameter involved. For finding Pressure the equation is P = nRT/V

To find Volume we have the formula V = nRT/P

Formula to determine moles is moles n = PV/RT

To Calculate Temperature we use the formula T = PV/nR


Ideal Gas Constant

Ideal Gas Constant is also known as Molar or Universal Constant. Usually it is denoted by the symbol R and is defined as the product of Boltzman Constant k with Avagadro's Number. The value of R in general is given by R = 8.31446261815324 m3·Pa·K-1·mol-1. However, the value of Ideal Gas Constant R might vary from unit to unit.
