A gas is confined to a cylinder under constant atmospheric pressure, as illustrated in the following figure. When the gas undergoes a particular chemical reaction, it absorbs 824J of heat from its surroundings and has 0.62kJ of P−V work done on it by its surroundings. What is the value of ΔH for this process? What is the value of ΔE for this process?

    qp = delta H
    Work done by the surroundings on the system is +
    dE = q+w.
