Pizza Rolls - State Functions

Does anyone remember the acronym that was used in the midterm review session to remember the state functions?
It was something like: "when you're Depressed watch TV..." ? ? ?
Or alternatively, does anyone have any other clever acronyms for state functions?
Thanks!

expansion vs nonexpansion

What was the difference between expansion work and nonexpansion work? In other words, what could create nonexpansion work? Compression?

Endothermic vs Exothermic

can someone confirm whether this is true: in the delta U = q + w , a negative value for q indicates an exothermic reaction within the system and a positive value indicates an endothermic one

Closed Systems

What were the ways that a closed system can be changed? Was it only by changing the temperature and/or volume?

Changing Usernames on Chem Community

How do we change our usernames on chemistry community? Does it matter that mine isn't my real name/my section?
