Now, onto boxes. Has anyone tried the box within a box technique? If so, did you surround the smaller box with insulating materials, or just keep in open? Several teams at my school have done one or the other with mixed success.
Are you proposing a Thermodynamic-ception?

My device is a box in a box. I don't have better results than those posted on this thread already, so based on my experience, it's not something that will keep a noticeable amount of heat from escaping.

Drawings of two designs we have. One is a box within a box. The other one is...something, I guess...
Excuse my terrible handwriting; I drew this on a laptop.
Box inside a box
The other design with a lot of layers
Yeah, if you guys don't understand the diagrams at all, ask.

Oops. I'll modify that design then...shouldn't be too big of an issue.

You might also want to think about what one does when one has something really hot and wants to cool it quickly.

You might want to rethink your design, because while water may be an adequate insulator it absorbs ALOT of heat, so unless you plan on using hot water(which I'm pretty sure is not aloud) then the water will be room temperature and almost certainly cool down the beaker even more than if you just had air

Here's a question, that I have been struggling to understand. "Two neighboring houses are built of the same materials, and one has twice the length, width and height of the other. Under ideal climatic conditions, what would be true about the rate that heat would have to be supplied to maintain the same inside temperature on a cold day. Compared to the small house, the larger house would need heat supplied at: 2x, 4x, 8x, 16x the rate?


Anybody know how to explain it?
