Charlotte Wakefield Investigation - Insulating Materials Introduction In this investigation I aim to find out which materials are the best insulators. This practical investigation involves investigating what kinds of materials are best at keeping water in a copper beaker warm. A material that prevents this heat loss is called an insulator. Insulators have to prevent three types of heat loss: · Conduction · Convection · Radiation Conduction - This is where heat energy passes through the walls of the copper beaker by making the particles of the beaker vibrate which makes the particles next to them vibrate causing the heat to pass through the walls of the beaker to the surroundings. Materials that are good thermal conductors tend to be good electrical conductors; metals such as gold, silver and copper have high thermal conductivity's and will conduct heat well. Materials such as glass are poor heat conductors. Convection - This is where the cooler water particles sink down...
