5. “Thermodynamics is an axiomatic science which deals with the relations among heat, work and properties of system which are in equilibrium.” OR “Thermodynamics is the science of the regularities governing processes of energy conversion.” OR “Thermodynamics is the science that deals with the interaction between energy and material systems.” Introduction Introduction on Thermodynamics Jignesh Chhatbar Mechanical Department

6. Introduction Basic concept of Heat Transfer Jignesh Chhatbar Mechanical Department Thermal Contact is when two substances can affect each other's temperature. Thermal Equilibrium is when two substances in thermal contact no longer transfer heat. Thermal Expansion takes place when a substance expands in volume as it gains heat. Thermal contraction also exists.

7. Introduction Basic concept of Heat Transfer Jignesh Chhatbar Mechanical Department Conduction is when heat flows through a heated solid. Convection is when heated particles transfer heat to another substance, such as cooking something in boiling water. Radiation is when heat is transferred through electromagnetic waves, such as from the sun. Insulation is when a low-conducting material is used to prevent heat transfer.

8. Introduction System, Surrounding & Boundary Jignesh Chhatbar Mechanical Department System :- “Selected quantity of matter or region in space for thermodynamic study is known as system.” Surrounding :-“Everything outside the system, which interacts with the system, is known as Surrounding of the system.” Boundary :- “The real or imaginary surface that separates the system from its surrounding is known as Boundary.”

10. Introduction Thermodynamics System Jignesh Chhatbar Mechanical Department Open system- If the system features the exchange of both energy and matter with its surroundings, it can be called an open system. Closed system- If the system can only exchange energy with its surroundings and cannot exchange matter with it is known as closed system. Isolated system- An isolated system is a thermodynamic system that cannot exchange energy or matter with its surroundings

11. Introduction Zeroth Law of Thermodynamics Jignesh Chhatbar Mechanical Department Thermodynamics, basically entails four laws : The Zeroth law deals with thermal equilibrium and establishes a concept of temperature.
