Re: Thermodynamics B/C
Also, k values are negative. The best k values are those that are closest to zero. Something like -0.0001 would easily win, and get 20 points.

Re: Thermodynamics B/C
Wouldn't a k value of -0.001 be better than -0.0001 because -0.001 is lower? And thus, a (hypothetical) k value of -1 would be even better, because it's even lower. K value closest to 0 isn't best, lowest k value is best.satvik03 wrote:Also, k values are negative. The best k values are those that are closest to zero.

I can't think of anything else to put here, so I just wrote this...

Re: Thermodynamics B/C
According to the rules, closest to 0 is best. This makes sense since a k value closer to 0 yields a lower temperature drop.nateDC wrote:Wouldn't a k value of -0.001 be better than -0.0001 because -0.001 is lower?

if -1 was the best k value i might as well bring a chunk of metal as my box...UTF-8 U+6211 U+662F wrote:According to the rules, closest to 0 is best.

Re: Thermodynamics B/C
Is stopping convection really going to make a difference in my k-value? I am thinking of adding a bunch of foam bits and pieces in between layers of foam and also around my beaker where there are gaps in insulation.

Re: Thermodynamics B/C
Thanks. By the way, is the foam color that I use going to change much? Right now, I have white-colored foam, so it doesn't absorb as much radiation from the surroundings. Is this more ideal than darker-colored foam?

Re: Thermodynamics B/C
It doesn't really matter that much. If you're going to talk about radiation though, use reflective foil/other like material to reflect radiation. Line the inside.
