The tendency of materials to expand in volume when heated is called Thermal expansion. It occurs due to the increased vibration of atoms and molecules as temperature rises. There are three types: linear expansion (length), areal expansion (area), and volumetric expansion (volume). Thermal expansion

Class 11 Physics Thermal Properties of Matter deals with the physical behavior of substances when heat is added or removed. The main topics include temperature and heat, measurement of temperature, thermal expansion (linear, areal, and volume), specific heat capacity, change of state (melting, boili

The Class 11 Physics Mechanical Properties of Fluids is a foundational topic that introduces students to the behavior of fluids under various forces. It holds significant importance in both school-level examinations and competitive exams like NEET and JEE. In the CBSE Class 11 Physics annual examina

As the name suggests, a p-n junction diode means an n-type and p-type semiconductor joined together. At the junction, they form a depletion region. In forward bias where n is connected to negative and p to positive, the barrier potential reduces, allowing the current to flow. In reverse bias, there
