Intensive and Extensive Properties (गहन और विस्तीर्ण गुण) by Anil Sir | Semester 3 | Paper 1 | Unit 1

In this unit, Anil Sir will cover the fundamental concepts of intensive and extensive properties, crucial for understanding the behavior of physical systems in thermodynamics and other branches of science. The key distinctions between these two types of properties lie in how they depend on the amount of matter in a system:

Intensive Properties (गहन गुण): These properties do not change with the size or amount of material in the system. Examples include temperature (तापमान), pressure (दबाव), density (घनत्व), and refractive index (अपवर्तनांक). These properties are characteristic of the material itself.

Extensive Properties (विस्तीर्ण गुण): These properties vary with the size or amount of the substance in the system. Examples include mass (द्रव्यमान), volume (आयतन), and total energy (कुल ऊर्जा). These properties are dependent on the quantity of material present.


This topic is essential for students to differentiate between properties that describe the quality of a substance (intensive) versus those that scale with quantity (extensive). Through real-life examples and interactive explanations, Anil Sir will help clarify these concepts in preparation for exams.

Make sure to focus on understanding how changes in the system affect both types of properties as it lays the foundation for further topics in thermodynamics and material science.
