Container a holds an ideal gas at a pressure of 5.0 x10^5 Pa and temperature of 300 K. It is connected with a thin tube (and a closed valve) to container B, with 4 times the volume of A. Container B holds the same ideal gas at a pressure of 1.0 x 10^5 Pa and a temperature of 400K. The valve is opened to allow the pressures to equalize, however the temp of each container is maintained. What then is the pressure in the two containers?
