can you please explain me what is thermal physics and how it is used in daily life? Also how can I find resources to read the same and practice it? how important is it when preparing for JEE?

Thermodynamics in common usage in engineering is the study of energy and its various interconversions from one form to another.Thermodynamics has several types of Applications in our daily life: Fossil-fueled steam power plants, Spark-ignition engines and Jet engines.

All types of vehicles that we use, cars, motorcycles, trucks, ships, aeroplanes, and many other types work on the basis of second law of thermodynamics and Carnot Cycle.

They may be using petrol engine or diesel engine, but the law remains the same.Even cooling machines, such as refrigerators and air conditioners, actually use heat, simply reversing the usual process by which particles are heated. The refrigerator pulls heat from its inner compartment-the area where food and other perishables are stored-and transfers it to the region outside. This is why the back of a refrigerator is warm.

All the refrigerators, deep freezers, industrial refrigeration systems, all types of air-conditioning systems, heat pumps, etc work on the basis of the second law of thermodynamics.

One of the important fields of thermodynamics is heat transfer, which relates to transfer of heat between two media. There are three modes of heat transfer: conduction, convection and radiation. The concept of heat transfer is used in wide range of devices like heat exchangers, evaporators, condensers, radiators, coolers, heaters, etc.

Thermodynamics also involves study of various types of power plants like thermal power plants, nuclear power plants, hydroelectric power plants, power plants based on renewable energy sources like solar, wind, geothermal, tides, water waves etc
