A piston filled with 0.04 mol of an ideal gas expands eversibly from 50.0 mL to 375 mL at a constant temperature of 37.0^(@)C. 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)

Answer»

Q=+208 J, w=-208 J
q=-208 J, w=-208 J
q=-208 J, w=+208 J
q=+208 J, w=+208 J

Solution :The PROCESS is isothermal expansion HENCE, q =-w
`Deltau=0`
q=+208 J
w=-208 J (expansion work).
