Well, mightn't it?"Heat is the motion fo molecules" is an a posteriori judgement; scientific investigation might have turned out otherwise. — p. 185
I highly doubt that "molecular movement" is a rigid designator — Moliere
But does temperature equate to (the sensation of) heat? — Banno
So we use the description, 'that which causes such and such sensations, or that which we sense in such and such a way', to identify heat. But in using this fact we use a contingent property of heat, just as we use the contingent property of Cicero as having written such and such works to identify him. — pp. 187-8
Temperature is a physical phenomena; in a gas it's directly related to the RMS average velocity of the molecules involved (contra ↪Metaphysician Undercover ). — Banno
So yes, it is necessarily the case that temperature equates to molecular kinetic energy. — Banno
