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
