GCSE Physics - Conduction, Convection & Radiation | How Heat Energy is Transferred (2026/27 exams)

Practice worksheet - GCSE Physi

⭐️ Check out our website https://www.cognito.org/ ⭐️ *** WHAT'S COVERED *** 1. Conduction * How heat energy is transferred through the collision of vibrating particles. * Why conduction is most effective in solids. * The concept of thermal conductivity, including thermal conductors and insulators. 2. Convection * How heat energy is transferred by the movement of particles in fluids (liquids and gases). * The process of fluid particles heating up, becoming less dense, and rising. * The formation of convection currents. 3. Radiation * How heat energy is transferred by infrared waves without the need for particles. * How heat travels through a vacuum, such as from the Sun to the Earth. * The principle that all objects both absorb and emit infrared radiation. *** EXAM BOARD SPECIFIC INFO *** AQA - Everything is relevant to your course!
