Master NEET Physics 2025: Thermodynamics First Law Solved Problem

Are you preparing for NEET 2025 and looking to master Thermodynamics? In this video, we break down a high-yield question based on the First Law of Thermodynamics, specifically focusing on the relationship between heat, internal energy, and work done in cylindrical systems.

What You Will Learn:

In this tutorial, we solve a specific problem involving two gases (A and B) in separate cylinders with movable pistons. You will learn how to:

• Apply the First Law of Thermodynamics formula: dQ = dU + dW [01:11].

• Understand how constant pressure and equal heat supply affect work done [01:26].

• Relate volume change to cylinder radius and displacement [02:01].

• Step-by-step calculation to find the ratio of radii when given displacement values [02:44].

Problem Breakdown:

The problem eXplores two systems where the heat energy supplied  and the change in internal energy  are identical. By isolating the work done , we demonstrate that the product of the cross-sectional area and the displacement remains constant. This leads us to the final ratio of for the radii given the displacements of and [02:58].

NEET 2025 Physics Solution Magnetic Moment of a Circular Coil

In this video we solve a specific physics question from the NEET 2025 exam. The lesson focuses on the chapter of electromagnetism. We explain how to calculate the ratio of magnetic moments for two different circular copper coils when they carry the same amount of current.

What You Will Learn in This Video

This tutorial covers the fundamental formula for the magnetic moment of a circular conductor. You will see how the magnetic moment relates to the number of turns the current and the area of the coil. We break down the math simply so you can understand how changing the radius of a coil affects its magnetic properties.

Key Topics Covered

• Understanding the magnetic field in a current carrying coil.

• The formula for magnetic moment using current and area.

• How to find the ratio of magnetic moments when radii are different.

• Step by step calculation for a common entrance exam question.
