When the state of a system changes from ...

When the state of a system changes from `A` to `B` adiabatically the work done on the system is `322` joule. If the state of the same system is changed from `A` to `B` by another process, and heat required is `50` calories of heat is required then find work done on the system in this process? `(J = 4.2 J//cal)`

A

98J

B

98.2J

C
