SUMMARY

The discussion centers on the Unruh effect as it relates to accelerated teapots and boiling water. It establishes that in an accelerated frame, such as that of a teapot, the liquid can boil due to two primary factors: the presence of blackbody radiation as described by the Unruh effect and the pressure exerted by acceleration, which raises the boiling point of the water. The temperatures derived from these two phenomena are distinct, indicating that the system does not achieve thermal equilibrium. Thus, the interaction between acceleration and temperature in this context is complex and multifaceted.

The liquid in an accelerated teapot is a function of its acceleration, so there are accelerated teapots where the water is boiling. This is the same for a non falling tea pot near a BH.
I sea two reasons for this:
a) The Unruh effect says that in the teapot frame there is around it a blackbody radiation of particles at a given temperature. there is an equilibrium between the teapot and the particles.
b) there is a pressure on the water due to the acceleration. the boiling temperature of a liquid depends on the pressure so the temperature comes from the acceleration. It does not need an external thermal bath.

Are these points of view exclusives?

The temperature in a) is not equal to the temperature in b). The temperature in a) depends on the Planck constant, unlike the temperature in b).
Both effects influence the total state of the liquid, so one can say that the system will have two temperatures. This really means that the system will not be in a thermal equilibrium.
