Rearrange the variable in the combined gas law to solve for P2.

Short Answer

Expert verified

The combined gas law forP2isP2=T2脳P1脳V1T1脳V2

Step by step solution

01

Given Information

We need to rearrange the variable in combined gas law to solve forP2.

02

Simplify

The combined gas law is given as:

P1脳V1T1=P2脳V2T2

Here,

P1is initial pressure,

role="math" localid="1652612308124" T1is initial temperature,

V1is initial volume,

role="math" localid="1652612331003" P2is final pressure,

T2is final temperature and

V2 is the final volume.

Now, in case if are asked to find the final pressure the combined gas equation will be rearranged as:

P1脳V1T1=P2脳V2T2T2脳P1脳V1=T1脳P2脳V2

For P2is equal to:

P2=T2脳P1脳V1T1脳V2
