At constant pressure, q = ΔH:


H=+q

  • q → (+) → heat is added

You may want to reference (Pages 172 - 176)Section 5.3 while completing this problem.

A gas is confined to a cylinder under constant atmospheric pressure, as illustrated in the following figure. When 0.460 kJ of heat is added to the gas, it expands and does 216 J of work on the surroundings.

A diagram shows a piston as containing a system consisting of H2 (gas) and O2 (gas).  The surroundings are the cylinder, piston, and everything else.  Energy can enter or leave the system as heat or as work done on the piston, but matter cannot enter or leave the system.


What is the value of ΔH for this process?
