In Fig, the energy stored in `C_(4)` is `27 J`. Calculate the total energy in the system.

Calculate the energy stored in a capacitor.

Calculate the energy stored in a capacitor?

During a process, a system absorbs 710 kJ of heat and does 250 J of work. Calculate the change in the internal energy of the system.

A system absorbs 400 J of heat and does work equivalent to 150 J on the surroundings. Calculate the change in the internal energy of the system.

A system loses 120 ) of heat and does 80 J of work. Calculate the change in the internal energy of the system.

In a process, 600 J of heat is absorbed by asystem and 300 J of work is done by the system. Calculate the change in internal energy of the system.
