0A piston filled with \( 0.04 \mathrm{~mol} \) of an ideal gas expands reversibly from \( 50.0 \mathrm{~mL} \) to \( 375 \mathrm{~mL} \) at a constant temperature of \( 37.0^{\circ} \mathrm{C} \). As it does so, it absorbs \( 208 \mathrm{~J} \) of heat. The values of \( q \) and \( w \) for the process will be :
\( (R=8.314 \mathrm{~J} / \mathrm{mol} \mathrm{K})(\ln 7.5=2.01) \)
(A) \( q=-208 \mathrm{~J}, w=+208 \mathrm{~J} \)
(B) \( q=+208 \mathrm{~J}, w=+208 \mathrm{~J} \)
(C) \( q=+208 \mathrm{~J}, w=-208 \mathrm{~J} \)
(D) \( q=-208 \mathrm{~J}, w=-208 \mathrm{~J} \)
