PAR you contribution the second paragraph in this section Temperature is a measure of specific energy not energy in general that is what needs to be made clear Temperature is somewhat comparable with specific gravity SG which is Kg m3 you would I hope never quote or use SG as kilograms unit of mass Temperature has a big brother called Entropy which is a measure of the distribution of energy and is by contrast an extensive property which is defined in the theory Statistical mechanics Temperature does not need statistical mechanics to define it it is one of the assumptions on which statistical mechanics is based
