What is the maximum temperature that can be measured?

[AngryPixel]

Hi guys help me..

My teacher asked me " Can we measure 15000 degree Celsius, If yes then how?, if no then why not and what is the maximum temperature that can be measured?"

I have searched google but didn't find a definite answer (or i didn't searched right way ). Please help me, i gotta answer him tomorrow.:help

I'm the last person on earth who should be answering physics questions. Nonetheless, you might find this link useful:

i meant on the earth dude.. like in industry etc

Well in reactors etcetera and in the new collider temperatures can exceed millions of degree's ...how they measure it though I don't know....

Logically, the maximum temperature that can be measured is the maximum temperature the element used to measure it can withstand. (Critical Point)

Metals have a high critical point. eg. Gold, Iron have critical points in excess of 6500 C

At certain atmospheric pressures, these may be further controlled.

Are you sure your teacher didn't ask you about the lowest temperature? :confused:

That's a no brainer
Absolute zero = 0K = -273.15 Celsius

I am sure.. He said he wants to know how to measure it inside a furnace which rises upto 15000 *C.

Thermocouple?

Tell the teacher than you use a high-capacity thermometer. That's what I would have done.

Sorry to bump this up.
A google search took me here.

This is what I found there:

Absolute zero is because temperature is because temperature is effectively how much energy each individual molecule has. If you give them more energy it gets hot if take energy out it gets cooler. Because something can have effectively zero energy you can’t take any more energy out of it. Then you can have a minimum temperature. You can put in as much energy as you like but it becomes faster. There isn’t really a maximum temperature.
