Physics - Kinetic Theory of Gases

Practise 58 TS EAMCET previous year questions on Kinetic Theory of Gases, compiled from papers spanning 2001 to 2025. Each question is pulled directly from the actual exam paper it appeared in, so you're practising in the exact style and difficulty TS EAMCET tests.

Kinetic Theory of Gases has been asked in 15 of the 24 years of TS EAMCET papers analysed (2001–2024), with 58 questions in all. 60% of them were easy, 29% moderate and 10% tough. Most of its questions came from 2021, with 8 questions that year. In the last three years (2022–2024) it had 18 questions across 17 papers, about 1.1 per paper.

The chapter's 4 topics are not weighted equally: Speed of Gas (20 questions, 34%), Gas Laws (15 questions, 26%), and Degree of Freedom and Specific Heat (13 questions, 22%) have been asked the most. Speed of Gas has also led over the last five years, with 14 questions. Gas Laws has produced the most tough questions (3).
