Question

How toprepare thermodynamics advance level what is weitage of different topics in it

Answer 1

1. Weightage: Heat and Thermodynamics forms about 8% weightagein JEE main and advanced making it an essential topic for a better rank. Chemical Thermodynamics, forms about a 5% weightage in JEE Advanced.
2. Previous trends: Questions are asked from different topics like adiabatic & isothermal process, entropy, enthalpy, absolute zero, calorimetry, laws of thermodynamics, conservation of energy, internal energy, isobaric, triple point. These are the important topics of thermodynamics. The most important part in chemical thermodynamics is thermochemistry i.e. enthalpy/entrapy changes during the course of a reaction.
3. Pattern of questions: Some of the laws and their applications are asked directly. Numerical as well as theoretical questions are asked from this chapter based on finding heat absorbed/radiated. Numerical part involves many inter-related steps as well as concepts, so develop proper skill to approach towards the solution. Questions are mainly asked from Work/energy done/transferred.
