Transmission of Heat Made Easy for JEE Students
🌡️ Transmission of Heat – JEE Made Simple Heat is a form of energy that flows from a hot object to a cold one. Just like water flows from high to low level, heat flows from higher temperature to lower temperature. But how does heat move? There are three main ways heat is transferred: --- 1️⃣ Conduction 🟢 Main Idea: Heat is transferred through solids without movement of particles. 📌 Examples: Heating one end of a metal rod makes the other end hot. Cooking using a steel pan. 💡 How It Happens: When one part of a solid is heated, its particles vibrate more. These particles pass their energy to neighboring particles. 🔍 Important Terms: Good Conductors: Metal (Copper, Aluminium, etc.) Bad Conductors (Insulators): Wood, Plastic, Air 🔥 Formula: Q=k.A(T¹-T²).T÷d Where: Q = heat transferred K= thermal conductivity A= area T¹-T²= temperature difference d= thickness T = time --- 2️⃣ Convection 🟢 Main Idea: Heat is transferred by the actual movement of particles ...
