Re: [Phys-L] let's define energy



???

In the simple case of an ideal gas, the temperature sets the average kinetic energy through the Boltzmann constant (J/K), but the temperature is not commonly considered "the energy".

Perhaps it would be helpful if the terms "dimensions" and "units" were defined. I am not aware of an interpretation that would make S=k ln(omega) a dimensionless quantity.

do you see temperature as a sort of energy?

Yes, absolutely. For example, in the expression

dE = T dS (under some conditions)

there is energy on the LHS. The energy on the RHS
comes entirely from the T, not from the dS.
