A gas can be taken from state a to c by ...

A gas can be taken from state a to c by two different reversible processes,`aimpliesc` or `aimpliesb=c`. During the direct process `aimpliesc, 20.0J` of work is done by the system and `30.0J` of heat is added to the system. During the process `aimpliesbimplies, 25.0J` of heat are added to the system. How much work is done by the system during `aimpliesbimpliesc`?

A

`5.0J`

B

`10.0J`

C

`15.0J`

D

`20.0J`
