A piston filled with 0.04 mol of an ideal gas expands reversibly from 50.0mL ot 375mL 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 ) ` ( In 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`
