What is Temperature?

SUMMARY:
Temperature can be defined in several ways, many of which are not completely accurate, but the first definition of Number 5, above, seems to almost fit our understanding and work reasonably well as an “Operational Definition” for the term.

However, the detail provided in the last reference (Number 6) gives a more complete understanding and shows that the word “proportional” really belongs in the definition. At least that’s the opinion of this website editor and publisher.

If you have another view, please let us know and, if it is persuasive, we will post here also. Just feedback in the comment section below website or by using the “Submit” button to send us a direct note..

Now, in case you’d not up on your physics or would just like a brief visual explanation, here’s a wonderful set of them from Eureka’s Heat and Temperature series that begins with the “Dance of the Molecules”:
