A gas is confined to a cylinder under constant atmosphericpressure, as illustrated in the following figure. When the gasundergoes a particular chemical reaction, it absorbs 825 J of heatfrom its surroundings and has 0.69 kJ of P-V work done on it by itssurroundings.

What is the value of delta H for this process?
