Second Law of Thermodynamics Class 12 Physics Notes is designed according to the updated syllabus of 2080 and it covers all the important portion of the chapter. Students can easily prepare their notes, study for test or exams by taking the help of class 12 Second Law of Thermodynamics Notes.
Chapter – 5
Second Law of Thermodynamics
The first law of thermodynamics deals about the conservation of energy. When a hot body placed in thermal contact with cold body, heat starts to flow from body at higher mean temperature to the body at lower mean temperature but never in the reverse direction.
If heat was made to flow from body at lower mean temperature to the body at higher mean temperature, energy would still be conserved. Yet it does not happen. Therefore, first law of thermodynamics can’t explain the direction of flow of heat
Chapter Overview
In this chapter we are going to learn the following concepts, ideas or topics;
Now let’s move on to the notes of second law of thermodynamics. The PDF given below contains all the notes which includes all the topics mentioned in the chapter overview. We request students to use the notes of Second Law of Thermodynamics wisely for the purpose of making notes and preparing for the board examination.
You have to scroll down the PDF to view all the notes of Second Law of Thermodynamics. This PDF contains 7 slides in total which contains all the required notes of second law of thermodynamics. It doesn’t contains the numerical problems so if you are searching for the numericals then you’ll find them in the next PDF given below.
Kelvin-Planck’s Statement
It states that ‘It is impossible to design a device that works on a cycle and produces no other effect other than heat transfer from a single body for the production of work”. leaThis statement is applicable to heat engines. In a heat engine, the working substance absorbs some heat from the source converts a part of heat into mechanical work and rejects the remaining part to the sink.
