Learn with States of Matter Notes and Score High in JEE Main 2025

States of Matter is the field of chemistry that explores the different physical forms in which matter can exist, such as gases, liquids, and solids. It delves into the properties, behavior, and transitions of these states, offering insights into the fundamental nature of matter.

The weightage of States of Matter in JEE Main is around 2-3%. This means that there are typically 2-3 questions asked from this chapter in the exam. Students can also expect direct questions from this section which makes it one of the scoring topics. Here are the few points that make the chapter high weightage. 

1. Essential Concepts in States of Matter

• Solid, Liquid, Gas, Plasma, and Bose-Einstein Condensate

Each state of matter has unique characteristics. We will explore the properties and applications of solid, liquid, gas, plasma, and the fascinating Bose-Einstein condensate.

• Phase Transitions and Intermolecular Forces

Phase transitions occur when matter changes from one state to another. We will discuss the factors influencing phase transitions and the role of intermolecular forces in determining the properties of different states of matter.

• Kinetic Theory of Matter and Molecular Motion

The kinetic theory of matter explains the behavior of particles in different states. We will delve into the molecular motion in solids, liquids, and gases.

2. Major Concepts in States of Matter

• Amorphous vs. Crystalline Solids

Amorphous and crystalline solids have distinct properties. We will compare and contrast these two types of solids and explore their applications in various fields.

• Melting Point, Boiling Point, Sublimation, and Deposition

Understanding melting point, boiling point, sublimation, and deposition is crucial in the study of phase changes. We will explain these concepts and their significance in changing states of matter.

• Compressibility, Viscosity, Density, and Diffusion

Compressibility, viscosity, density, and diffusion are important properties of matter. We will define and elaborate on these terms, exploring their significance in understanding the behavior of different states of matter.

• State Diagram and Van der Waals Forces

A state diagram visually represents phase transitions. We will discuss the role of Van der Waals forces in the behavior of gases.
