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 $37.0^{\circ }\text{C}$. 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) (ln7.5 = 2.01)

• A

  $\text{q}=-208\text{J}\text{,}\text{w }=+208\text{J}$
• B

  $\text{q}=+208\text{J}\text{,}\text{w}=+208\text{J}$
• Correct answer
  C

  $\text{q}=+208\text{J}\text{,}\text{w}=-208\text{J}$
• D

  $\text{q}=-208\text{J}\text{,}\text{w}=-208\text{J}$

Hence, the correct answer is option: 'C'.
