Thermodynamic Temperature

[@jonathanlister5644]

Thank you so much Professor 50 years ago when I studied physics I hadn't a clue about this! Your discussion was crystal clear.

Please explain (or give an example of) how to measure Q1/Q2 without using the empirical concept of temperature. Thanks!

Sir, we know the triple point of water. How can we calculate Q1 and Q2 to get the temperature T1?
