For an isolated system, DeltaU=0. What will be the value of DeltaS? |
| Answer» Solution :Consider the example of TWO gases contained separately in two BULBS CONNECTED by a stop-cock and isolated from the SURROUNDINGS as an example of an isolated system. On OPENING the stop-cock, the two gases mix up, i.e., the system becomes more disordered. This implies that `DeltaS gt 0`. | |
