I have to do this for a CIM test in Chemistry (junior in high school), and nobody knows how to do it.

I don't think we're really expected to find something accurate, but I at least need to do SOMETHING

He said they are upward to around 1500 degrees, so that makes things really difficult. The only thing I can think of would be to melt iron and say, hey it's at least 1500 degrees C, but I don't know how long that will take or if I will have access to iron.

Would you be allowed to expose a classmate to it?

[ChairmanPoo]

Is it a problem or a "practical knowledge"? You can tell the temp setting of a bunsen burner by the flame color. Blue, it's fully burning and it's at it's hottest. Yellow, it's doing a partial combustion and producing CO. It depends on the adjustment of the air feeder.

... I SUPPOSE that the color might be enough to tell the temp in a scale of some sort, but I am not sure about how to go about it.

EDIT: so yeah. I am full of win

It's very very hot.  I know this from accidentally touching freshly-smoothed glass tube ends.

Very hot.  Like a billion degrees at least.

Try black body radiation? Heat something up, like a piece of tungsten, then accurately determine the color (frequency) of the light it radiates using a prism and colored paper, and compare that to the table.

It's the most convoluted way I can think of.

Beaker of water with a thermometer in it?

[redacted123]

The water would just boil away before even getting close to the temperature.

[Jreengus]

Hmmm I suppose so, I didn't really that one though.

Oooh wait I have an idea! A BIG beaker of water with a thermometer in it. =p

I could be talking out my ass here but if you boil a certain amount of water can't you work out from that and knowing how much energy it would take to boil the water and the time it takes to boil the amount of energy the burner is giving off per second or whatever and from that the temperature?

[Neonivek]

Why don't you just use pressure to determine temperature?

[sonerohi]

Kinda like what thatguyyouknow said, what about a sealed container with a non-burning gas in it and a thermometer? Make sure to account for gas expansion though.

You could just get an old mercury or alcohol thermometer, and make it explode.  Then report to him that it's "really hot"

[ChairmanPoo]

Too late you suckers, you lost the game!

[eerr]

Ooooh burn!

We haven't really done any of the color stuff before.

I think we're supposed to do something with specific heat.

So maybe I can heat some kind of metal for a few minutes, until its about the temperature of the flame, and then put it in a water bath with a known mass and temperature

T = (c x m x T)/(m x c)

So if I can find the mass and change in temperature of the water, and I know the mass and specific heat or the metal, I should be able to use the final temperature of the metal (same as water) to find the initial temperature.

Does this sound like it would work? How could I heat the metal without melting everything?

You can't melt something with liquid water in it silly.
