Just internal.

Just the internal, which is why I think it's not really worth it.

If you added ice water to both beakers, it would be obviously right to add the max all the time. There'd be nothing to think about.

As it is, try the ice water bonus. You know how your device scores without ice water. Try it with, and pretend you're competing with yourself without the ice. Who wins?

I have really strong opinions about the ice bonus, and I agree with this. Here is what I know:
1. We tested ice bonus vs. not ice bonus at various times, temps, and volumes. We found the ice bonus to “beat” the non ice bonus every time.
2. At states our device performed equally or better than every non-ice bonus team.
3. Our prediction at nats was only 0.1 degrees off. And this was not a surprise.
4. Troy used the ice bonus.

What was your heat retention Alex? Ours without bonus was around 1.9 I think.

Ice water would only need to be 38 or higher to beat this, which should be pretty easy.

Actually, our final temperature was only 34.5. It’s possible our device simply wasn’t very good (and yours definitely was).

Congrats on 2nd!

Lol. When you see that the team you beat at state for thermodynamics get 2nd at Nats...

The test at nats was over three times as long and much more difficult than at state. Even with that, though, it still was manageable under time constraints. :)

Yeah, it was pretty hard. We didn’t come close to finishing.

Did anyone have results significantly affected by High Altitude? Something we had not accounted for

Ask Pikachu as she helped out with Div. B Thermo at Nats and might know.

The History section on the Nats test was a lot more difficult than I was expecting.
