Answer:
Both: T1 = T2 (P1V1/P2V2)
V2 = V1(T2/T1)(P1/P2)
Explanation:
To answer this question, we are going to take the expressions in question as;
i) T1 = T2 (P1V1/P2V2)
ii) V2 = V1(T2/T1)(P1/P2)
We are required to determine whether the expressions are correct variation of the Combined Gas Law.
- Combined gas law puts together the Boyle's law and the Charles's law.
- According to Boyle's law, the volume of a fixed mass of a gas is directly proportional to the absolute temperature and inversely proportional to the pressure.
- Therefore; V α T/P
Hence;
P₁V₁/T₁=P₂V₂/T₂
From the equation, we can rearrange it to get the expressions;
T1 = T2 (P1V1/P2V2)
V2 = V1(T2/T1)(P1/P2)
Thus, both expressions are correct variations of the combined gas law.
