This question already has an answer here:

Are temperature increases ever discrete in nature, or is it a continuous variable?

If a discrete case exists, is there any material that exhibits particularly strange behavior?

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.


If you stick with the Statistical Mechanics formalism, then temperature is discrete.

Entropy S is $ S = k_B\ln(\Gamma) $, where $\Gamma$ is the number of available quantum states,

and temperature is

$T = \frac{dE}{dS} $ , where E is the total kinetic energy of the system.

Since every quantity there is discrete, so is temperature.
