The ideal gas equation

• Boyle's law

  pressure (p) x volume (v) = constant
• Charles' law


  pressure (p) / temperature = constant (or) volume (v) is directly proportional to temperature (t)
• Gay-Lussac's law (constant volume law)


  Pressure (p) is directly proportional to temperature (t) (or) pressure (p) / temperature (t) = constant

  pressure (p) x volume (v) / temperature for a fixed mass of gas
• Ideal gas equation


  P (Pa) V (m3) = n (JK-1 mol-1) R (JK-1 mol-1) T (K)

  R = 8.31 JK-1 mol-1
