Randall D. Knight — A Macroscopic Description of Matter: Problem 58

Containers A and B in FIGURE P18.58 hold the same gas. The volume of B is four times the volume of A. The two containers are connected by a thin tube (negligible volume) and a valve that is closed. The gas in A is at 300 K and pressure of \(1.0 \times 10^5 \text{ Pa}\). The gas in B is at 400 K and pressure of \(5.0 \times 10^5 \text{ Pa}\). Heaters will maintain the temperatures of A and B even after the valve is opened. After the valve is opened, gas will flow one way or the other until A and B have equal pressure. What is this final pressure?
