Read questions carefully twice and then look at the options before solving a question. Current Electricity. According to the CBSE syllabus, Class 11 Physics Revision Notes for the subject Thermodynamics is prepared. If certain quantity of heat dQ is added to a system, a part of it is used in increasing the internal energy by dU and a part is use in performing external work done dW. Thermodynamics also deals with macroscopic behaviour instead of microscopic behaviour of this system and understanding of such topics is very important to solve questions from this section. Thermodynamics is concerned with macroscopic behavior rather than microscopic behavior of the system. The effect of naturally occurring processes is always to increase the total entropy (or disorder) of the universe.
