Temperature Task

[Dark Sabre]

Paradox took apart an outdoor dial thermometer and I took apart my oven thermometer, so we have some pics on the Bimetallic strip Wiki

Someone pointed out that I was dumb and thermostats with mercury switches do have bimetallic coils...so pics of that will be up as soon as my thermostat is back together...

Are peltiers even legal this year? There's a specific list of electric components we're allowed to use, and it doesn't include diodes (except for LEDs).

Nope.

This came up at the coach's clinic I ran yesterday: don't use a mercury switch. Liquid mercury is not an authorized liquid. Only water and vinegar are allowed.

You can still use the bimatallic coil.

Are thermocouples allowed at all?

How can we effectively cool down an object QUICKLY!!!!!!!!!!!!!!!!!!!!?????????????????????????????

[ichaelm]

I'm pretty sure that's the part you're supposed to figure out on your own...

But if it helps, perhaps you could make something hot, and then blow a fan on it?

Really hot things cool down really quickly, and it's really easy to make something really hot. (Think bimetallic strip, as Dark Sabre suggested.)

[DeltaHat]

You can also discharge a can of compressed air. Those things get very cold as they decompress - ideal gas law and all.

Just don't turn the can upside down. The liquid that squirts out is not authorized

If we do use a bimetallic strip for this and we heat it up with a Nichrome wire what kind of gauge would work the best? i hear theres a like hair thin 40 gauge and a much thicker like a coat hanger 14 gauge which one would heat the bimetallic strip up the fastest with the least amount of voltage?

also i have never used a bimetallic strip, when they cool would they cool with enough force to toggle or push in a swtich? like the one pictured in http://scioly.org/wiki/Bimetallic_strip ?

thanks for the help!
