Oh naah, I love you soo much
There is a dash in between the wiedemann and Franz😊

I am a named law in physics.
I express a relationship between two physical properties of a solid material.
I relate a thermal property and an electrical property of a metal.
I am in the conductivity business.
I am the law that gives the temperature dependence of the ratio of the thermal and electrical conductivities of a metal.
Answer: Wiedemann-Franz law

Owwww😭😭😭😭😭

Let's continue 😊

I am a principle that is of interest to both physicists and chemists.

Damn🔥🔥🔥🔥

You're wrong ❌

My bad😂😂😂

Or????

I am a principle that is of interest to both physicists and chemists.
I am encountered in statistical theories of matter.
I am derived in kinetic theory.
My currency is half the Boltzmann constant times absolute temperature.
For a given temperature, I assign equal energy to each degree of freedom.
Answer: Equipartition principle (or Principle of equipartition of energy)

the Equipartition theorem

I am an experiment that was performed towards the end of the nineteenth century.

Damnnnn🔥🔥🔥🔥🔥

This one is correct 😂😂😂

I am an experiment that was performed towards the end of the nineteenth century.
I was billed to prove the existence of something that is now known not to exist.
Such was my success that a new approach to physics emerged from my results.
I am named for the two scientists who first performed me.
I am just an experiment that saw the end of the luminiferous ether and provided a nail for its coffin.
Answer: Michelson-Morley experiment

That's crazy 😂😂😂
