In a certain process, `400J` of work is done on a system which gives off `200J` of heat. What is `DeltaU` for the process?

Delta U= + 200 J for a system that gives off 200 J of heat and

In a certain process. 678 J of heat is absorbed by a system, while 294 J of work is done on the system. What is the change in the internal energy for the process?

During a process work equivalent to 400J is done on a system which gives out of 125J of energy.The change in internal energy is (A) 525J (B) 375J (C) 275J (D) 200J

During a process work equivalent to 400J is done on a system, which gives out of 125J of energy. The change in internal energy is

During a process work equivalent to 400J is done on a system, which gives out of 125J of energy. The change in internal energy is
