Conduction is the way in which energy is transferred (through heating by contact) from a hot body to a cooler one (or from the...
Let's think about conduction in solids first. Here each particle vibrates but ends up going nowhere over the longer term. This...
The paper starts to spin because the heat of your hand heats up the air. This sets up a convection current in the air which...
Hot water is less dense than cold water so it rises into the top bottle while the cold water sinks into the bottom bottle...
Our first collection of videos gives teachers and coaches of physics a preview of the training we offer ahead of this term's live support sessions.
