Physics - Thermodynamics

Practise 8 VITEEE previous year questions on Thermodynamics, compiled from papers spanning 2009 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 VITEEE tests.

Thermodynamics has been asked in 5 of the 18 years of VITEEE papers analysed (2006–2024), with 8 questions in all. 25% of them were easy, 63% moderate and 13% tough. Most of its questions came from 2009, with 3 questions that year. In the last three years (2022–2024) it had 2 questions across 1 paper, about 2 per paper.

The chapter's 3 topics are not weighted equally: Thermodynamic Processes (4 questions, 50%), First Law of Thermodynamics (2 questions, 25%), and Heat Engine, Refrigerator and Second Law of Thermodynamics (2 questions, 25%) have been asked the most. Over the last five years the most frequent topics have been First Law of Thermodynamics (1) and Thermodynamic Processes (1). Thermodynamic Processes has produced the most tough questions (1).

3.Is Thermodynamics an important chapter for VITEEE Physics?

Thermodynamics has appeared in 5 of the 18 years of VITEEE papers covered here, with 8 questions across 5 papers - about 2 per paper it appears in.

4.What is the difficulty level of Thermodynamics questions in VITEEE?

Of the 8 questions analysed for this chapter, 25% are easy, 63% moderate and 13% tough. 2009 had the most, with 3 questions.

5.Which topics in Thermodynamics should I focus on?

These topics have carried the most weightage in Thermodynamics:

  • Thermodynamic Processes - 4 questions (50%)
  • First Law of Thermodynamics - 2 questions (25%)
  • Heat Engine, Refrigerator and Second Law of Thermodynamics - 2 questions (25%)
  • Thermodynamic Processes has produced the most tough questions (1).
6.Is Thermodynamics's weightage in VITEEE going up or down?

Across all 5 papers analysed, Thermodynamics has averaged about 1.6 questions per paper. In the last three years (2022–2024), that average has risen, at about 2.0 questions per paper. Use the year-wise numbers on this page for the exact trend before you decide how much time to give it.
