I’ve heard a few times now in various scientific fields, mainly experiments, about things getting as hot as the sun.
How is this possible? Surely if you do something and you create heat that is that hot it would melt anything surrounding it?
Would love to know how this works 🙂

Another interesting way to look at temperature is the “black body radiation”.
The emitted light of a heated material has a color that is depended on the temperature of the material. The more red: cool, the more blue: hot.
This is what we call “color temperature”. Color temperature is defined in Kelvin instead of degrees C, but with these high numbers you can treat K and C as identical to each other.
We see the sun as white, this is about 5000K-6000K.
Incadencent bulbs are quite yellow compared to the sun about 3000K-4000K. This is the actual temperature of the wire inside the bulb.
A plasma cutter as someone else mentioned looks very blue its temperature is about 14000K.
The temperature of cinema projector lamp is about the same as the sun, as they tried to match the sun, so that white looks white.
