# 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.

### Calculator of Combined Gas Law

 I want to calculate Конечная температура (Tf)Initial Volume(Vi)Initial Pressure(Pi)Initial Temperature(Ti)Final Volume(Vf)Конечное давление (Pf) Initial Volume(Vi) = L Initial Pressure(Pi) = kPa Initial Temperature(Ti) = K Final Volume(Vf) = L Final Pressure(Pf) = kPa Final Temperature(Tf) = K

### Formuls of Combined Gas Law

Gas Equation: PiVi/Ti = PfVf/Tf

where,

• Vi = Initial Volume,
• Pi = Initial Pressure,
• Ti = Initial Temperature,
• Vf = Final Volume,
• Pf = Final Pressure,
• Tf = 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,

Tf = (Ti x PfVf) / PiVi
= (5 x 7 x 2) / (12 x 10)
= 0.58

Hence, final temperature is0.58
