Question

Three thermally insulated containers of equal volume are connected together by thin tubes of negligible volume so that gas can flow from one container to the next when a valve between them is open. Initially, the pressure and temperature in each container is at the same value P_o and T_o, respectively.

The valves between the vessels are opened, and thermal insulation is removed from two of the vessels. Then two vessels are surrounded by heat reservoirs so that their temperatures are maintained at 1.85T_oand 1.7T_o while the third remains at T_o. What is the final pressure of the system when mechanical equilibrium is reached?
_______________P_o

Initially, the pressure and temperature in each container is at the same value P_o and T_o, respectively.

The valves between the vessels are opened, and thermal insulation is removed from two of the vessels. Then two vessels are surrounded by heat reservoirs so that their temperatures are maintained at 2T_o and 2.5T_o while the third remains at T_o. What is the final pressure of the system when mechanical equilibrium is reached?

____ Po

P= ( m1 P0 + m2 * P 2P0 + m3 * 2.5P0)/(m1+m2+m3) because p is proportion to T for contant volume

=1.5 P0
