Thermodynamics Weightage in JEE Mains 2025 is expected to be 15%. For JEE Mains 2025, 4 to 5 questions are expected to be asked in the exam with major topics being Heat Transfer, Laws of Thermodynamics and Thermodynamic Processes.
Thermodynamics Weightage in JEE Mains 2025: Thermodynamics not only forms an integral part of both physics and chemistry separately but it is also equally crucial in understanding concepts that combine topics from both subjects. Each year, there are 4 to 5 questions directly asked from thermodynamics making it one of the most important topics to score well in the JEE Main exam. Moreover, since the questions from this topic are mostly conceptual and formula-based it is expected that students will score well on this particular topic. To have a complete idea about the JEE Mains 2025 Weightage of Thermodynamics candidates can take a look in this article.

FAQs
In the reduced syllabus of the JEE Mains exam, most topics have been removed from Chemistry with 6 units completely removed and around 20 topics removed from 5 other units.
Though it's not wise to skip any topic for the JEE Main exam, however, if one is short on time, candidates can leave low-weightage topics and invest their time on the important topics.
If the candidates are seeking to get admission into the top-listed IIITs, and NITs, then it will be difficult for them with such a percentile score. However, the reserved category candidates can try their luck to get admission into the IIITs or NITs with 92 percentile marks.
The hardest topics in the JEE Main Physics exam comprise Heat and Thermodynamics, Electrostatics and Magnetism, Mechanics, Modern Physics, Current Electricity, Optics, and Electromagnetic Induction.
No. Candidates should base their JEE Main exam preparation on the previous year's question papers, mock tests and practice tests to ace the JEE Main exam with high marks.
170 marks in the JEE Main exam equals to 98.85+ percentile, which in itself is a very good percentile. Through this, candidates can secure admission into the top premier institutes in India such as NITs, IIITs, and GFTIs.
In the JEE Main Physics paper, chapters with the most weightage are Electrostatics, Optics, Current Electricity, and Mechanics whereas the moderate weightage chapters comprise Magnetism, Modern Physics, Waves, and Thermodynamics.
