Heat is occasionally
called a process quantity<span>, for the reason that it is defined in the background of a
process by which energy can<span> be transported.
</span>The consequence of heat on water hinge
on whether the energy is touching into the water (endothermic)
or touching out of the water (exothermic). When water molecules
get energy, the average speed of the molecules rises; this is computed
as a temperature change if enough energy is
gained.</span>
