To investigate conduction in a metal rod

WebbGlass is a very poor heat conductor. It has one of the lowest possible heat conduction a solid (without air trapped in it) can possibly have, this is mostly due to its lack of ordered … WebbThe cup is made from thick plastic with lots of tiny air bubbles in it. He asks the class why the cup is so good at keeping a hot drink warm. Three suggestions are made. It contains air which is a poor thermal conductor. The air is trapped in tiny bubbles so very little convection is possible. The plastic is a poor thermal conductor.
