Zeroth Law of Thermodynamics – The Basis for Temperature Measurement Zeroth Law of thermodynamics is very simple to understand. It says that when two bodies are separately in thermal equilibruim with a third body, then the two bodies are also in thermal equilibrium with each other. This law has been used as the basis for measurement of temperature.
First Law of Thermodynamics: Mankind’s Dependency on Nature for Energy Humans beings consider themselves as highly creative people since they have carried out most of the developments in the present day world. However, for the most basic needs we are still entirely dependent on nature. Let's see how first law of thermodynamics mocks all our claims of creation of work.
Definition and Laws of Thermodynamics Since early days mankind has been utilizing energy in various forms and knowingly or unknowingly converting it from one form to the other. Thermodynamics is the branch of science and important subject of Mechanical Engineering which studies conversion of energy from one form to the other.
What is a Thermodynamic Process? When any of the properties of the system such as temperature, pressure, volume etc change, the system is said to have undergone thermodynamic process. Various types of thermodynamic processes are: isothermal process, adiabatic process, ischoric process, isobaric process, and reversible process.
