📘 Class 10 Chemistry – Chapter 2: Matter | Section 2.6: Sublimation Welcome to our detailed video lecture on Sublimation, the sixth section of Chapter 2, Matter, in the Class 10 Chemistry curriculum. This lecture is designed to provide students with a clear understanding of the sublimation process, its applications, and its significance in the study of matter. 🔍 Key Topics Covered: Definition of Sublimation: Understanding the process by which a substance transitions directly from a solid to a gas without becoming liquid. Examples of Sublimable Substances: Common examples like iodine, ammonium chloride, naphthalene, benzoic acid, and camphor. Applications of Sublimation: Including its use in purification, everyday products, and industrial settings. Uses of Sublimation in Drugs: Used to purify pharmaceutical compounds that can sublime, like camphor. Important in freeze-drying (lyophilization) for preserving heat-sensitive drugs such as vaccines and antibiotics. Helps in the formulation of inhalable medications for quick delivery to the lungs. Used to create porous, fast-dissolving tablets to improve drug absorption. 🎯 Learning Objectives: By the end of this lecture, students will be able to: Define sublimation and describe the process clearly. Identify substances that undergo sublimation. Understand the practical and industrial applications of sublimation, including its role in drug manufacturing. 🧪 Practical Demonstration: Watch a hands-on experiment with ammonium chloride showcasing the direct change from solid to gas during sublimation. 📚 Resources: Download the FBISE Class 10 Chemistry Textbook (NBF) More Class 10 Chemistry Video Lectures 🔔 Stay Connected: Like, share, and subscribe for more educational videos.
