Does the temperature of a body depend on the frame from which it is observed?

No, the temperature of a body doesn’t dependent on the frame from which it is observed. Thermal motion can be considered as the random motion of the particles such as atoms, molecules etc. correlated with its thermal energy. The thermal energy of particles is in turn related to the temperature of that object. Thermal motion differs from ordinary mechanical motion because the particles within the object move in a random manner. The thermal motion doesn’t dependent on the frame from which it is observed. As the driving mechanism behind temperature is the thermal motion, we can say that the temperature is also independent of the frame of reference.
