Free NEET Physics Questions-Thermodynamics and Kinetics

Important NEET Questions for Physics

If you are preparing for NEET, you just cannot focus on Biology. To crack NEET exam, you need to clear the minimum cut-off for Physics as well as Chemistry. NEET Physics is a nightmare for most students. With 45 questions for marking, your goal should be to get as many correct to improve your overall score in NEET. 

In Physics, you must be competent in theoretical concepts and as well as in numerical problems. Moreover, you will need an application-oriented approach and understanding of the concepts to get good marks in Physics. So, to solve the numerical problems of NEET physics, it is not enough to develop a learning habit by going through the books. You must apply your basic learnings to a wide variety of applications. 

So, if you are wondering how to go about it, then practicing Physics NEET Questions is one way to do it. You should solve as many questions as possible from a chapter to know how well you have understood the concepts. That way, you can solve both theoretical and numerical physics problems with ease in the NEET exam. In this article, we are providing you with 10 free sample NEET questions from the Thermodynamics and Kinetics chapter in Physics. You can solve the questions to know where you stand in your NEET preparation.
