Hi everyone, How do u measure temperature, let's say of a car bulb without using a thermometer?


Your ideas are all welcomed.
Thanx

What is the context of your question? Is this for schoolwork?

Berkeman's question notwithstanding, do you know anything about black body radiation? I guess it'd probably be best to dial it back a bit and follow-up from dlgoff's question and ask if you are approaching this more from a practical or theoretical perspective, and whether or not you mean contact vs non-contact.
