Re: Thermodynamics B/C

What methods do you guys use to find certain conditions you havent tested. For example @ 50 mL say you have 60 C and 70C data points, then how would you find say 63 C?

Re: Thermodynamics B/C

What exactly do you guys put in your binder besides history? Also, how often do you use your binder?

Re: Thermodynamics B/C

How efficient are your devices? Under the conditions of 150 ml and a starting temperature of 90 degrees Celsius, I got an ending temperature of 58 degrees Celsius after 30 minutes. Also, what materials are you guys using a cap for the beaker of water? By starting temperature of 90 C do you mean the...

Re: Hovercraft B/C

How close do you guys get to 15 seconds, and how consistently do you get that?

Re: Thermodynamics B/C

How exactly do you guys do history? This is my first time doing an event with history in it and every competition something new just seems to show up how do I make sure to get them next time?

Re: Thermodynamics B/C

I like how this forum is mainly dedicated towards the device and attaining the best prediction and thermal score, but the most important part of this event is the test. At MC Barrons I got 1st in Prediction, 2nd in Heat Retention, but LAST (that how dumb I am, and we had the biggest binder XD, I gu...

Re: Thermodynamics B/C

Does the testing time start from the moment you receive water or from the moment the beaker is placed in the device? Can you use your own thermometer to measure the initial water temperature (after it is poured into device) before making the prediction? Thanks! You are allowed to use your own therm...

Re: Hovercraft B/C

But there will be varied amts of friction between the hover and railings... That's been a really big problem for us, eventually our hovercraft just stops moving because of the friction. Honestly, I've kind of given up on timing and am heavily relying on weight scores, and our hovercraft moves well ...

If Giancolli is a starting point, what would you recomend to study afterwards?
