Convection occurs when particles with a lot of heat energy in a liquid or gas move and take the place of particles with less heat energy. Convection in a liquid Convection in a liquid can be seen ...

Finally, the problem of heat transfer by natural convection for both laminar and turbulent boundary layer flow over a vertical hot wall will be described. Finally, some applications of the transport ...

This clip shows how a vacuum flask prevents heat loss ... Students could draw a diagram or build a model of to show how conduction, convection and radiation are prevented. They could experiment ...
