Also, the rules say "Teams may submit up to 4 plots for scoring. Teams may be asked by the supervisor to submit
them prior to the tournament.". Are they giving points on how good the graphs are or are they just merely checking over them to make sure that you did some work and aren't just guessing? Would I have points taken off for submitting less than 4 plots?

Re: Keep the Heat B/Thermodynamics C
I believe they check the graphs to make sure you have axes, units, labels, etc. and I'm sure they would state the temperature of the cold water, and you can calculate from there to see if its worthwhile or not.mingtian wrote:Is anybody going to take up the bonus point challenge and add ice water to their beaker?

Re: Keep the Heat B/Thermodynamics C
Scoring rule 5- at 5(c) very clearly lays it out. You can submit up to 4. One is chosen by the ES for scoring. max graph score is 10 pts; the amounts to be deducted for what may not be in the graph is stated, item by item.

Re: Keep the Heat B/Thermodynamics C
For people who have already competed in this event, when you impound your device, do they actually check to see if it fits in a 15 cm box? Because our device is just barely 15 cm, maybe 1 mm over, and it has a latch on it which could make it difficult to fit into a 15 cm box. Would this be a problem and would we have to remake the whole device?

Re: Keep the Heat B/Thermodynamics C
They do indeed actually check. I believe most event supervisors just make a 15^3 box and slip it over your device. If it fits, you're good. If not...well...

Oh wow, I don't think ours is going to fit... This sucks Well, I better start rebuilding! Thanks!!foreverphysics wrote:They do indeed actually check. I believe most event supervisors just make a 15^3 box and slip it over your device. If it fits, you're good. If not...well...

Re: Keep the Heat B/Thermodynamics C
I am wondering if I should use all the space provided or actually minimize the space. I thought that a smaller space would be better since it would keep the heat confined as long as it actually insulates. Small rooms and houses are easier to insulate than larger ones so I was thinking along the same lines for this event. Anyone have insight into this?

Re: Keep the Heat B/Thermodynamics C
That is a slightly different situation. Larger houses and rooms have more surface area and are therefore harder to insulate. However, a larger thermo device generally just means more insulation, although you could potentially have problems with an increased heat capacity depending upon what insulation is used.sr243 wrote:I am wondering if I should use all the space provided or actually minimize the space.

Re: Keep the Heat B/Thermodynamics C
So we have to use a 250 mL beaker right? We can't use 100 ML beaker? And if that's true, does anyone happen to have the dimensions of a 250 mL beaker on them?
