Essentially this. Does the ice water bonus give enough points to counteract the heat retention factor loss and can you predict it properly. only by tests can you find whether it does.arv101 wrote:Those 5 points could help if you can predict it right.I don't really know but 10 points made the difference of like 10 rankings at an invitational so the 5 points could give you an upper edge.mkroy128 wrote:Ice Water Bonus (IWB) = (volume of ice water in ml /10) points
Teams may elect to add up to 50 mL of water from an ice bath to their internal beaker immediately after
receiving the hot water for bonus points. Each team may choose their own volume.
Do any of you know how to effectively use ice water in this event to your advantage? Is 5 points extra really worth the ice water, along with more careful predictions of the final insulator beaker? Or is it useless?

Re: Thermodynamics B/C
In the Thermodynamics Rules, it states that we submit graphs and/or tables. Does that mean we can just do tables and not the graphs?

Re: Thermodynamics B/C
I can suggest tests..the thing is, you will have no chance taking them just using what you learned in your middle school science class...that's just not the way it works..you have to study thermodynamics first...then you can take testsbt03 wrote:Practice tests are great and all.
That is, when you find one that is out of the world to a normal physics student and then one which is relatively comparable to a physics/chemistry student that knows gas laws and basic thermodynamics.
TL;DR: Who can suggest a practice test that is reasonable for the 2018 B Division?

Re: Thermodynamics B/C
In addition to another Scioly-er's question on the forums, is there a fixed temperature for the ice water, because if there is, then tests can (with difficulty) allow you to predict exactly what the end temperature will be. If not, then some serious math will be involved, and I'd need to pull out a LOT of numbers (such as the k factor of my materials, the thickness of given materials and so on). I understand that I'm technically already supposed to be doing that (as room temperature variation can cause a difference in end temperature), but I just wanted to know if anyone could offer me any clarification on this.

Re: Thermodynamics B/C
As far as I know there is no fixed temperature. However, under ideal conditions ice water will always be 0°C.JoeyC wrote:In addition to another Scioly-er's question on the forums, is there a fixed temperature for the ice water, because if there is, then tests can (with difficulty) allow you to predict exactly what the end temperature will be.

While it is inevitable for there to be some degree of contamination, in my opinion, it is safe to assume the ice water will be 0°C.

Re: Thermodynamics B/C
In my science class, we ran an experiment to observe water rising (purpose was to graph and prove latent heat for phase changes) and we tried to get the temp as low as possible...the lowest we got was 1.3 degrees Celsius... I would assume the temp is somewhere from 1-1.5 Cvjindal wrote:As far as I know there is no fixed temperature.
