Chemistry problem
« on: December 11, 2010, 12:16:32 AM »
How would I go about to start this problem? I don't know how to start this problem. Does the formula q= mc delta T apply? See problem below.

A closed, uninsulated system fitted with a movable piston was assembled in which so no matter is exchanged with the surroundings. Introduction of 483 J of heat caused the system to expand, doing 320 J of work in the process against a constant pressure of 101 kPa (kilopascals). What is the value of ΔH for this process?

Thanks for any help

At constant pressure, enthalpy change is equal to heat.
