Figure shows two rigid vessels A and B, each of volume `200 cm ^(3)` containg an ideal gas `(C_v = 12.5 JK ^(-1) mol^(-1))`. The vessels are connected to a manometer tube containing mercury. The pressure in both the vessels is 75 cm mercury and the temperature is 300k. (a) `(5-0 J)` of heat is supplied to the gas in the vessels.(b) `(10 J)` to the gas in the vessels B. Assuming no appreciable transfer of heat from A to B calculate the dufference in the heights of mercury in the two sides of the manometer. Gas constant `(R = 8.3 JK^(-1) mol^(-1))`
