What is thermodynamics?
(N/A) Thermodynamics is the branch of physics that deals with the concepts of heat,temperature,and the interconversion of heat and other forms of energy.
Thermodynamics is a macroscopic science that deals with bulk systems and does not concern itself with the molecular constitution of matter.
Thermodynamic description involves relatively few macroscopic variables of the system,which can usually be measured directly. For example,a microscopic description of a gas would involve specifying the coordinates and velocities of all the molecules of the gas.
Through thermodynamics,macroscopic quantities of a gas such as pressure $(P)$,volume $(V)$,temperature $(T)$,mass $(m)$,and composition can be measured.
