4.6
· 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) Answer: The limitation of this animation is the heat source. The solid is being heated by a match making the amount of heat uncontrollable.
Task 2
· Try the quiz on the Cooking animation
· Extension: what's the mistake in the description of convection? Answer: The mistake in the animation is that the heated molecules do not cool down, shrink and sink. Instead, the heated molecules rise, forcing the cooler molecules at the top to go down and replace it. This then creates a "convection current"
