L-3 Exploring Mixtures & their Separation | Ch-5 Class 9 Science New NCERT | Exploration | Tarif Sir In this lecture, Tarif Sir continues Chapter 5 — Exploring Mixtures and Their Separations from the New NCERT Exploration textbook for Class 9 Science (Session 2026–27). Building on the concentration terms covered in Lecture 2, this session dives into Pause & Ponder questions, Solubility of Substances, the Effect of Temperature on Solubility, and the Solubility Curve — complete with NCERT-based numericals and graph-based questions solved step by step. 📌 What You'll Learn in This Lecture: Quick revision of all three concentration terms: Mass by Mass %, Mass by Volume %, and Volume by Volume % Pause & Ponder Question 1: Talcum Powder & Zinc Oxide — solving % m/m numerical Pause & Ponder Question 2: Orange Juice Concentrate — solving % V/V numerical Pause & Ponder Question 3: Vinegar & Glacial Acetic Acid — making a 5% V/V solution Understanding real-life meaning of concentration expressions (e.g., 2% m/m ZnCl₂, 3% m/V H₂SO₄) What is Solubility? — Definition with sugar-water example Effect of Temperature on Solubility: Solid solute in liquid → Solubility increases with temperature Gas solute in liquid → Solubility decreases with temperature (cold drink example) Saturated vs Unsaturated Solutions Solubility Curve — graph of Solubility vs Temperature NCERT graph-based questions on Compound A and Compound B solved 🎓 Useful for Board Exams of: CBSE | RBSE | MPBSE | HPBSE | UBSE 👨‍🏫 About the Teacher: Tarif Sir (@TarifBhayana-9th10th) teaches Class 9 and Class 10 Science in Hindi with a focus on concept clarity, NCERT alignment, and board exam preparation. All topics are explained with real-life examples and step-by-step problem solving. ⏱️ Timestamps: 0:00 — Introduction & Recap of L-1 and L-2 2:19 — Quick Revision: Three Concentration Terms 4:21 — Pause & Ponder Q1: Talcum Powder (% m/m Numerical) 8:30 — Pause & Ponder Q2: Orange Juice Concentrate (% V/V Numerical) 14:22 — Pause & Ponder Q3: Vinegar from Glacial Acetic Acid (% V/V) 19:06 — Real-life Meaning of Concentration Expressions 21:25 — Solubility of Substances — Definition 23:32 — Effect of Temperature on Solubility 26:33 — Saturated and Unsaturated Solutions 27:36 — Solubility Curve (Solubility vs Temperature Graph) 28:42 — NCERT Graph Questions on Compound A & B Solved 32:14 — Summary & Recap of the Full Lecture 🔍 Class 9 Science Chapter 5 | New NCERT Exploration 2026-27 | Mixtures & Separation | Solubility | Concentration Terms | Tarif Sir | CBSE RBSE MPBSE HPBSE UBSE | Hindi Medium Science | Pause and Ponder Questions | Solubility Curve | Saturated Solution | Mass by Mass Percentage | Volume by Volume Percentage | Zinc Oxide Talcum Powder | Acetic Acid Vinegar | Effect of Temperature on Solubility Class 9 Science Chapter 5, Exploring Mixtures and Their Separation, New NCERT Exploration 2026-27, Solubility of Substances, Effect of Temperature on Solubility, Solubility Curve, Concentration Terms Class 9, Mass by Mass Percentage, Volume by Volume Percentage, Mass by Volume Percentage, Saturated Solution, Unsaturated Solution, Pause and Ponder Questions, Zinc Oxide Talcum Powder, Acetic Acid Vinegar, CBSE Class 9 Science, RBSE Class 9 Science, MPBSE Class 9 Science, HPBSE Class 9 Science, UBSE Class 9 Science, Tarif Sir, Class 9 Science Hindi
