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.
