Chemistry - Thermodynamics (C)

Practise 30 Manipal (MET) previous year questions on Thermodynamics (C), compiled from papers spanning 2010 to 2024. 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 (C) has been asked in 15 of the 15 years of Manipal (MET) papers analysed (2010–2024), with 30 questions in all. 60% of them were easy, 33% moderate and 7% tough. Most of its questions came from 2018, with 4 questions that year. In the last three years (2022–2024) it had 3 questions across 3 papers, about 1 per paper.

The chapter's 4 topics are not weighted equally: Laws of Thermochemistry and Enthalpy Change (11 questions, 37%), First Law and Basic Fundamentals of Thermodynamics (9 questions, 30%), and Third law of thermodynamics (8 questions, 27%) have been asked the most. Over the last five years the most frequent topics have been First Law and Basic Fundamentals of Thermodynamics (3), Laws of Thermochemistry and Enthalpy Change (2), and Third law of thermodynamics (2). Laws of Thermochemistry and Enthalpy Change has produced the most tough questions (1).
