It is stated from a source that thermal physics is like an 'umbrella' for covering 3 other subjects, and the 3 topics are thermodynamics, statistical mechanics, and kinetic theory, and soooo, how does thermal physics is in relation to heat and temperature ?
Other than heat and temperature-which is in relation to heat related subjects ,what other heat relation subjects are there?
These are some questions I don't know yet as it sound too profound or maybe i haven't learnt anything about it yet.
