Class 10th Chemistry New Book 2026 || Chapter 14 || Lecture 5 || Heating and Cooling Curve || Part 2 Class 10th Chemistry | Unit 14: States of Matter & Phase Changes | Lecture 05 Assalam-o-Alaikum Students! Welcome back to ChemHub. In this video, we are continuing our journey through Unit 14: States of Matter & Phase Changes from the New Book 2026. This is Lecture # 05, and today we are covering Heating & Cooling Curves (Part 2). In Part 1, we learned the basics and broke down the heating curve. In this lecture, we will shift our focus to Cooling Curves and master how substances release heat energy during phase transitions. We will analyze the graph step-by-step, explaining condensation and freezing points, and look at how the temperature behaves during these changes. Understanding these graphs is key to scoring full marks in your Matric board exams, as graphical conceptual questions are frequently asked. 📌 What you will learn in this video: Detailed analysis of a Cooling Curve graph Understanding Condensation & Freezing Points on a curve Concept of Exothermic Phase Changes (releasing heat energy) Key differences between Heating and Cooling Curves Expected board exam conceptual questions from Unit 14 Make sure to watch till the end, draw the curves in your notebooks for practice, and drop any confusion or questions in the comments below! 🔔 Subscribe to ChemHub for complete, chapter-wise conceptual lectures of the New 2026 Chemistry Book! 👍 Don't forget to Like, Share, and Subscribe to help other students!
