Ice Cubes on a Conductor and an Insulator
| Content Provider | WatchKnowLearn |

| Description | This brief experiment includes 2 ice cubes: one is placed on a cork mat (an insulator) and one on a metal surface (conductor). Because the metal is a conductor it is able to conduct thermal energy to the ice cube (and take it from the surroundings) much more quickly than the cork mat. The ice cube on the metal has completely melted while the cork mat has hardly made a dent. This experiment also demonstrates that air (as with any gas) is a good insulator. If air was a good conductor, then the ice on the metal might have melted marginally faster; the effect would not be nearly so pronounced. The video plays at 16 times normal speed; the ice cube on the metal took just over 8 minutes to melt. No audio. |
