Physics - Thermodynamics

Practise 28 Manipal (MET) previous year questions on Thermodynamics, compiled from papers spanning 2010 to 2021. Each question is pulled directly from the actual exam paper it appeared in, so you're practising in the exact style and difficulty Manipal (MET) tests.

Thermodynamics has been asked in 9 of the 15 years of Manipal (MET) papers analysed (2010–2024), with 28 questions in all. 61% of them were easy, 36% moderate and 4% tough. Most of its questions came from 2014, with 5 questions that year.

The chapter's 3 topics are not weighted equally: Thermodynamic Processes (19 questions, 68%), First Law of Thermodynamics (7 questions, 25%), and Heat Engine, Refrigerator and Second Law of Thermodynamics (2 questions, 7%) have been asked the most. Thermodynamic Processes has also led over the last five years, with 6 questions. Thermodynamic Processes has produced the most tough questions (1).
