Combined Gas Law

Combined gas law is the combination of Charles's law, Boyle's law, and Gay-Lussac's law. It states that the ratio between the pressure-volume product and temperature is a constant. In this calculator, the initial and final volume, pressure, temperature can be calculated alternatively with the other known values.

Formuls of Combined Gas Law

Gas Equation: P_iV_i/T_i = P_fV_f/T_f

where,

V_i = Initial Volume,
P_i = Initial Pressure,
T_i = Initial Temperature,
V_f = Final Volume,
P_f = Final Pressure,
T_f = Final Temperature.

Example of Combined Gas Law

If the initial and final volume is 12, 2, initial and final pressure is 10, 7 and initial temperature is 5,

T_f = (T_i x P_fV_f) / P_iV_i
= (5 x 7 x 2) / (12 x 10)
= 0.58

Hence, final temperature is0.58
