Intro

The  variables that would be in the numerator P1V1T2.

The variables that would be in the denominator V2 and T1

Explanation:

Combined Gas law is the summation of Boyle's law, Charles Law and Gay Lussac's law.

According to Combined Gas Law the ratio of pressure into volume by temperature at absolute temperature is constant.

The variables will be listed as following in the reaction:

V1 (initial volume)

P1 (initial pressure)

T1 (initial temperature)

V2 = (final volume)

P2 =(final pressure)

T2 = (final temperature)

these variables are related as:

=

This equation is termed as combined gas law equation.

When final pressure i.e P2 is to be calculated the equation will be arranged as:

P2 =

in denominator we will have = final volume into initial temperature

in numerator we will have = initial pressure into initial volume into final temperature.
