SUMMARY

The discussion centers on the relationship between relativity and heat, specifically whether a moving object's temperature requires more heat to increase than an object at rest. It concludes that, within the rest frame of the object, the mass increase due to speed does not necessitate a larger amount of heat for temperature changes. The transformation of temperature fields between inertial frames is a key consideration in understanding this phenomenon.

I was wondering: relativity predicts that the mass of an object increases with its speed. Does this imply that a moving object would require a larger amount of heat in order to increase its temperature than an object at rest?

Not in the rest frame of the object. The question is: how does a temperature field transform between inertial frames?
