Homework Statement



Calculate DeltaE of a gas for a process in which the gas absorbs 42J of heat and does 14J of work on the surroundings. (ie the gas expands)

Homework Equations


DeltaH=DeltaE-Q


The Attempt at a Solution


42=deltaE-14

DeltaE=+28J

This is one of the last problems on my chem review and it just seems too easy. If anyone could verify my process that would be great.
