A rigid container is filled with a mixture of three gases: A, B and C. The pressure gage reads PT. The container is evacuated and filled with an amount of gas A equal to that in the original mixture. The gage now reads PA. This process is repeated for gases B and C with the pressure gage reading PB and PC respectively. How is PT related to PA, PB, and PC? What assumptions are made? Assumptions: 1) constant volume, 2) no heat loss, 3)PT>TA,TB,TC -these are the assumptions i can think of as of right now. are there any other relevant ones? As for the question How is PT related to PA, PB, and PC? Answer: PT = PA + PB + PC - is this the right aswer or it's more complicated than that?
