When you are cooking you know the bass is going to get hot because you are transferring energy form of heat to it. And you know you have to eat it otherwise you body will have no way of producing work to get you through your daily job.
Thermodynamics can be easily seen every day.When you wake up and make a coffee from coffeemaker 1st law applies there then you take milk out of fridge heat engine in reverse!!. You switch on the t.v. it gets heated up a bit joules heating.You head outside home,you feel hot/cold because of heat transfer.You start your car.And we can go on and on finding thermodynamics at work everywhere! Right from your cellphone,a.c. to your own body exchanges heat with surroundings.
All types of vehicles we use like cars, motorcycles, trucks, ships, aeroplanes, and many other types working on the basis of second law of thermodynamics and Carnot Cycle. It is also the basic working principle in petrol engine or diesel engine.
Renewable energy is a subject area of thermodynamics that involves studying the feasibility of using different types of renewable energy sources for domestic and commercial use.
One of the most important field of thermodynamics is heat transfer which is related 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 ex-changers, evaporators, condensers, radiators, coolers, heaters, etc.
Thermodynamics also involves study of 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,
All types of air and gas compressors, blowers, fans, run on different thermodynamic cycles.
There are many applications of thermodynamics in Refrigeration and Air conditioning like, refrigerators, deep freezers, industrial refrigeration systems, all types of air-conditioning systems, heat pumps, etc. Works on the basis of the second law of thermodynamics.
