    Change in I.E. for a reversible process

    yea that is what i meant about work. thank you so much for your help hearing the solution now i feel so dumb for not seeing that earlier because the change in internal energy is equal to ΔQ not Just the heat entering the system and then if the process was irreversible the change in entropy of...

    Change in I.E. for a reversible process

    So would it be Qh - Qc + Work = ΔI.E.

    Change in I.E. for a reversible process

    Homework Statement A system absorbs QH = 481 J of heat reversibly from a hot reservoir at temperature TH = 370 K, and gives off QC = 155.4 J of heat to a cold reservoir at TC = 156 K. During this process, W = 90.9 J of work is done by the system. a) Find ΔIE, the change in internal energy...
