Question

What is the combined gas law formula ?

Answer 1

P = pressure, V = volume, T = absolute temperature k = constant.

Answer 2

Explanation:

The combined gas law is given as:

$\frac{P_{1} V_{1} }{T_{1} } = \frac{P_{2} V_{2} }{T_{2} } = \frac{P_{n} V_{n} }{T_{n} }$

When the ideal gas law is reduced reduced, the General gas law or the combined gas law is obtained.

    let n = 1

                       from PV = nRT

                             $\frac{PV}{T}$ = R (constant ) if n=1

therefore:

$\frac{P_{1} V_{1} }{T_{1} } = \frac{P_{2} V_{2} }{T_{2} } = \frac{P_{n} V_{n} }{T_{n} }$

Where P is the pressure of the gas

           T is the temperature of the gas

            V is the volume of the gas
