Q. No.A piston filled with 0.04 mol of an ideal gas expands reversibly from 50.0 mL to 375 mL at a constant temperature of 37.0ºC. As it does so, it absorbs 208 J of heat. The values of q and w for the process will be-
(R = 8.314 J/mol K) (ln 7.5 = 2.01)
| 1. | q = +208 J, w = -208 J | 2. | q = -208 J, w = -208 J |
| 3. | q = -208 J, w = + 208 J | 4. | q = +208 J, w = + 208 J |
