Shouldn't temperature have units of J instead of K (since it measures the average kinetic energy of a body)?
I was just curious about something. Shouldn't temperature have units of J instead of K since it measures the average kinetic energy of a body?
That's an interesting question. The unit of Kelvin (K) is actually derived from the unit of energy - joules (J). One Kelvin is defined as the amount of temperature change equivalent to one joule of energy per mole of substance. So, in a way, temperature is already indirectly measured in joules.
