Question

Which of these expressions are correct variations of the combined gas law?

Answer 1

Both p2=p1(t2/t1)(v1/v2) and p1v1t2=p2v2t1

Step-by-step explanation:

Answer 2

The combines law of gas is:

P1 * V1 P2 * V2
---------- = -----------
T1 T2

So, you can obtain many equivalent valid forms depending on the variable that you solve for.

These are some examples:

Solve for T1:

T1 = T2 * (P1 * V1) / (P2 * V2)

Solve for V2:

V2 = V1 * (T2 / T1) * (P1 / P2)

Solve for P1:

P1 = P2 * (T1 / T2) * ( V2 / V1)
