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

both

Both: T1 = T2 (P1V1/P2V2)

         V2 = V1(T2/T1)(P1/P2)

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.

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.

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.
