· 4.6 recall that energy transfer may take place by conduction, convection and radiation Task 1
· Try the animation: particle model - conduction
· Extension: what is the limitation of this animation? (Check your answer with the Heating a Solid animation) It doesn't show the slight increase in volume when solid is heated.
Task 2
· Try the quiz on the Cooking animation
· Extension: what's the mistake in the description of convection?
It isn't moving molecules transfer heat through liquid or gas.
Due to the energy given by heat, the molecules near the fire get hotter and therefore, less dense. Less dense material rise to the top where the density is greater (due to colder temperature).
