Define Watt:
The unit, defined as one joule per second, measures the rate of energy conversion or transfer.
The rate at which energy is generated or consumed and hence is measured in units
the rate at which work is done when an object's velocity is held constant at one meter per second against constant opposing force of one newton.

Which of these is not one of Maxwell's stipulations for the definition of heat?
It is something which may be transferred from one body to another, according to the second law of thermodynamics.
It is a measurable quantity, and thus treated mathematically
Heat refers to a process of transfer of energy between a system and its surroundings other than by work or transfer of matter.
