IB Physics SL B.1.13 Convection
Practise explaining convection with density changes in fluids or plasmas, and linking unusual water density behaviour to circulation and survival under ice.
How this is tested
- outline a convection cycle by linking heating to lower density and rising fluid, with cooler denser fluid sinking
- explain why ice floating insulates water below, using water's density anomaly and the sinking of 4 degrees C water
