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^(@)C`. As it does so, it absorbs `208 J` of heat. The value of `q` and `w` for the process will be:
`(R=8.314J//molK)(ln 7.5=2.01)`

A

q=+208 J, W=-208 J

B

q=-208 J, W=-208 J

C

q=-208 J, W=+208 J

D

q=+208 J, W=+208 J
