# Three thermally insulated containers of equal volume are connected together by thin tubes of negligible volume...

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 Po and To, 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 1.85Toand 1.7To while the third remains at To. What is the final pressure of the system when mechanical equilibrium is reached?
_______________Po

Here is what I solved before, please modify the figures as per your question. Please let me know if you have further questions. Ifthis helps then kindly rate 5-stars.

Initially, the pressure and temperature in each container is at the same value Po and To, 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 2To and 2.5To while the third remains at To. 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
