In a process, 701 J of heat is absorbed by a system and 394 J of work is done by the system. What is the change in internal energy for the process ?

Text Solution

Verified by Experts

As per the first law of thermodynamics
`Delta U= q+w`
`= 701 + (-394)`
`= 307` J
Where `q= +701` J
`w=-394` J
`Delta U = (?)`
