Re: Thermodynamics B/C
Interesting. I will take this into account next year

Wait the rules don't say anything about the material right?TheChiScientist wrote:Wait a minute! I keep hearing all this talk of different beakers.Are you, people implying that the rules allow different material beakers?If so what type of beakers are you people using? I am using Pyrex Beakers.
What did the thermometer say to the graduated cylinder?

The rules say "2 identical, unaltered, glass or plastic, standard (height~1.4 times the diameter) 250 mL beakers;"arv101 wrote:Wait the rules don't say anything about the material right?TheChiScientist wrote:Wait a minute!

Re: Thermodynamics B/C
However, they don't usually check the height of the beaker rule; I've seen quite a few plastic pyrex beakers that violate that rule but are still allowed to be used in competition by the event procters

Re: Thermodynamics B/C
Interesting but then that means plastic beakers are better insulators

But it doesn't matter because your external beaker is also plastic.TheChiScientist wrote:Interesting but then that means plastic beakers are better insulators

Re: Thermodynamics B/C
I don't think the 1.4 rule is supposed to be extremely specific. It's just so people don't come in with graduated cylinders or something like that.
It probably matters less, but I think you'd have to do some testing to see if it doesn't matter at all. But certainly its effect is tiny, if at all.CookiePie1 wrote:But it doesn't matter because your external beaker is also plastic.TheChiScientist wrote:Interesting but then that means plastic beakers are better insulators

Re: Thermodynamics B/C
When you say that the plastic beakers violate the rule you mean because of their height/ dimensions right? Its not because of its material or company right?JoeyC wrote:However, they don't usually check the height of the beaker rule; I've seen quite a few plastic pyrex beakers that violate that rule but are still allowed to be used in competition by the event procters

Re: Thermodynamics B/C
Yes, their heights aren't near 1.4 times their diameters; these are mainly the wide plastic pyrex beakers.
