What is Thermodynamics?
The word thermodynamics was coined by William Thompson (Lord Kelvin) in 1749.
It comes from the Greek words: therme (heat) and dynamis (power).
The name heat-power is appropriate because thermodynamics developed from efforts to explain the conversion of heat into power by steam engines.
