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.

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.

Well to my expert knowledge and my exquisite calculations i think the the negative ion # 412 is the key to sucess
