Thermal expantion in solid || 3d animated explanation || 11th physics

When solids are heated, they expand! 🔥📏 This phenomenon is called thermal expansion. In this video, we explain how solids expand on heating, the three types of expansion (linear, area, and volume), and the role of the coefficient of expansion. You’ll also learn real-life applications, like why railway tracks have gaps, how bridges use expansion joints, and why electric wires sag in summer. Perfect for physics students and curious learners! 🌡️ Welcome to VisualLearning – where education meets creativity! 🎥✨ We create high-quality animated videos that simplify complex topics in Physics, Chemistry, Biology, and Engineering. Our mission is to make learning visual, interactive, and easy to understand for students from Class 9 to 12 and beyond. On this channel, you’ll find: 🔹 Animated explanations of science and engineering concepts 🔹 Step-by-step problem-solving guides 🔹 Real-life applications of theories 🔹 Simplified learning for exams and competitive preparation Whether you’re a student, teacher, or curious learner, VisualLearning helps you see education differently. 🚀 📩 Contact Us: 📧 Email: [email protected]
