I was so confused as to why 2 whole parts of the FRQ asked for a vertical line. I thought I was doing something wrong.

Do you need to have the heated water bath?

Hey Allen, for the PV diagram and the internal energy diagram question, would it be better to draw the internal energy line 1.5 times greater than the PV line as U = 3/2 PV and V stats constant?

For the graphs with the straight line, is it okay to draw them from the X-Axis?

[reemanreeman]

could you plot just Power transfer vs change in temp and then solve for k from the slope?

Watching these and realizing the stupid mistakes I made is just so aggravating, but theres nothing I can do about it now so might as well just forget about in until july comes and then be mad then

[adityaayyappan]

I converted J/s to W (watt). Would that work?

[hunterliften]

wouldn't the units be kelvin instead of celcius as per the table given?
