Three gaseous systems G1, G2, and G3 satisfy thermal equilibrium conditions: (I) when G1 and G2 are in equilibrium, P1V1 - P2V2 + αP2 = 0; (II) when G1 and G3 are in equilibrium, P3V3 - P1V1 + βP1V1/V3 = 0. Which relation is valid when G2 and G3 are in thermal equilibrium according to the Zeroth Law of Thermodynamics?
- 1P3V3 + P1V1(β/V3 - 1) = 0
- 2P1V1 = P2V2 = P3V3
- 3P3V3 + (P2V2 + αP2)(1 + β/V3) = 0
- 4P3V3 - (P2V2 - αP2)(1 - β/V3) = 0✓
Correct answer
P3V3 - (P2V2 - αP2)(1 - β/V3) = 0
