Question

For any thermodynamic system, there is a characteristic function called internal energy. The variation of that internal energy (ΔU) between any two states can be determined by the difference between the amount of heat (Q) and work (w) exchanged with the external medium. What is the increase in the internal energy of a system if it is supplied with 785 Joules of heat and a work of 935 Joules is applied?
