A system absorbs 800 J of heat and system works equivalent to 900 J by expanding. The value of `Delta U` for the system is

A system absorb 600 J of heat and work equivalent to 300 J on its surroundings. The change in internal energy

A system absorb 600 J of heat and work equivalent to 300 J on its surroundings. The change in internal energy

A system absorbs 600J of heat and work equivalent to 300J on its surroundings. The change in internal energy is:

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.

One mole of a gaseous system absorbs 100 J of heat and does work equivalent to 50 . J . Calculate the change in the internal energy of the system.

A system absorbs 600J of energy and does work equivalent to 400J J of energy. The internal energy changes
