Insights on Zeroth Law of Thermodynamics & its connected concepts :

• framed after First and Second Law of Thermodynamics.
• It is the basis for measurement of Temperature.
• Zeroth law of Thermodynamics defines Absolute Temperature.
• Ideal Gas or Perfect Gas is a function of Absolute Temperature only.
• In Throttling process, Enthalpy remains constant and Temperature is constant throughout the process but it is not a Isothermal process.
• Absolute Zero Temperature is reached when motion at molecular level is stopped.
• Temperature is an Intensive property(Independent of extent of mass).
• The unit of Temperature in S.I unit is Kelvin.
• Temperature is a property and which is defined as a point function and NOT path function.
• In Hyperbolic process Temperature remains constant, which is called as Isothermal process in which pressure is inversely proportional to the volume.
• A Thermometer works on the principle of Zeroth Law of Thermodynamics.
