A piston filled with `0.04` mole of an ideal gas expands reversible from `50.0mL` at a constant temperature of `37.0^(@)C` . As it does so, it absorbs `208J` of heat. The value of `q` and `W` for the process will be `(R=8.314J//molK` , `1n7.5=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`

Text Solution
