First, our icebreaker.
We're all underclassmen
We're all sceince-y
We're all in freshmen housing
We're all on facebook
We're all jealous that it's 77 degrees in California.
Now the meat of the workshop
Work done on the system + heat absorbed on the system, is the 1st law of thermodynamics.
ΔE=q+w
In an exothermic reaction the system will lose energy but temperature will rise, because your thermometer measures the released heat.
If work is done by system, the heat is negative (there is a loss of heat) Imagine exercising, you lose heat through your skin.
ΔH=q under constant pressure
Hess' law
ΣΔH(total) = ΣΔH(products) - ΣΔH(reactants)
q=mCΔT
