Episode 5 — Heat Transfer

Investigating Convection

Learners will be able to:

• Describe an investigation using potassium permanganate to demonstrate convection currents in water • Interpret observations of convection currents in a heated liquid • Explain why hot particles rise and cool particles sink in terms of density • Apply an understanding of convection to solve a real-life problem, such as positioning a heater and an air conditioner in a room
