Last year state, the test wasn't on Thermo, the event supervisors didn't give us the correct room temperature, had to restart the lab portion, and had to measure the temperature after everyone was gone (because they restarted it), and from the looks of it they measured the final temperature incorrectly.
All the good teams failed and the weak guys lucked out. and guess what? THAT MADE OUR SCHOOL NOT PLACE.
fun times. fun times.

Ouch, isn't there an appeal process over in Texas?

Don't know, but the thing was over, and the appeal process would probably take wayy too long. We weren't going to go to nats anyways. but still. we lost a state trophy by 2 points. But that's just how it is sometimes. :(

Sadly, yes. How could they mess up so bad as to not even have the test over the correct materials? What was it over??

Maxwell distribution (this is somewhat related, but the questions it asked were NOT related to , a tiny bit of thermo.,some mechanical physics. It didn't have any history or really even focus on one topic, just a whole bundle of random stuff.
The test was really weird, as evidenced by the fact that none of the top teams really place well in div C

And in div B only one of the teams placed well
http://outreach.science.tamu.edu/tso/2018/2018_BDivisionResults.pdf
Plus, as I said, the way that the lab was run make it really easy to suspect that the final temperatures were measured wrong somehow.

Can confirm that thermodynamics at state was terribly ran. The fact that they wouldn't let us measure the initial temperature of the water and instead telling us that the "temperatures would be accounted for for all teams" only added more frustration to the event. Also, the test was essentially two pages of trivia and little to no physics.

Will Gibbs free energy and all that stuff be on the exam?
The biologist speculates, "What's the meaning of life?"
The physicist asks, "In the universe, does matter really matter?"
The chemist replies, "I shall find solutions to both questions."

Just look at the rules, It has all of the topics that will be on the test. But from my experience, no. I haven't seen it ever on a thermo test.

For Division C it could (should) be. Division B, probably not.

That would explain why i've never seen it, I guess.

Gibbs Free Energy is Div C only, I haven't seen it on any Div B tests.

Gibbs free is pretty easy. Just include a table denoting what happens for each temperature-enthalpy scenario.

B-divisioners aren't tested on enthalpy or entropy so I don't think it's really applicable anyway

Does anyone know what a good Total Score would be? I was thinking maybe around mid 70's is competitive? But I'm not sure.
