Question

Chemistry

Which equation agrees with the ideal gas law?

Choices:

V1/T1=V2/T2

V1n1=V2n2

P1n1=P2n2

P1/P2=T2/T1

I got impatient and guessed, but got it right. Answer is the first one.

**Answer: first option V₁/T₁ = V₂/T₂**

**Explanation:**

1) The ideal gas equation is

**PV = nRT.**

2) R is the Universal Constant of gases, so ... it is constant.

3) When the amount of gas is the same (n is constant) and the pressure does not change (P is constant), the equation becomes:

**V / T = nR/P = constant.**

That means that

**V₁ / T₁ = V₂ / T₂ = V₃ / T₃ ....**

So, the option 1 has been proved.

Note that that is

**Charles' law.**
