Chemistry - States of Matter
Practise 23 KCET previous year questions on States of Matter, compiled from papers spanning 2007 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 KCET tests.
States of Matter has been asked in 17 of the 20 years of KCET papers analysed (2007–2026), with 23 questions in all. 61% of them were easy, 39% moderate and 0% tough. Most of its questions came from 2011, with 3 questions that year. In the last three years (2024–2026) it had 1 question across 3 papers, about 0.3 per paper.
The chapter's 6 topics are not weighted equally: Kinetic theory of gases (7 questions, 30%), Mixture of gases (5 questions, 22%), and Real Gases and Van der Waal's Equation (5 questions, 22%) have been asked the most. Over the last five years the most frequent topics have been Gas laws and Ideal Gas Equation (2) and Real Gases and Van der Waal's Equation (1).
