An ideal gas in a cylinder is separated by a piston in such a way the entropy of one part is `S_1` and that of the other part is `S_2`. Given that `S_1 gt S_2`. If the piston is removed then the total entropy of the system will be:

A

`S_1+S_2`

B

`S_1 xx S_2`

C

`S_1-S_2`

D

`S_1/S_2`

A mass less piston divides a thermally insulated cylinder into two parts having volumes V = 2.5 litre and 3 V = 7.5 litre. 0.1 mole of an ideal gas is confined into the part with volume V at a pressure of P = 10^(5) N//m^(2) .

A masslesss piston divides a closed thermallyy insulated cylinder into two equal parts. One part contains M = 28 g of nitrogen. At this temperature, one-third of molecules are dissociated into atoms and the other part is evacuated. The piston is released and the gas fills the whole volume of the cylinder at temperature T_(0) . Then, the piston is slowly displaced back to its initial position. calculate the increases in internal energy of the gas. Neglect further dissociation of molecules during, the motion of the piston.
