Is Air a Good Insulator? This experiment investigates the loss of heat through different insulating materials. Heat is loss through conduction, convection and radiation these three procedures could be acting on the experiment whilst I am working on it. Conduction: conduction usually occurs in metals they allow energy to spread through them quickly. It is the transfer of heat energy without the substance itself moving. Convection: Convection mainly occurs in liquids and gases. As the liquid or gas rises up it replaces the colder, dense regions. Convection is the transfer of heat by the movement of the substance itself. Radiation: Hot objects releases infra-red radiation, the hotter the object gets the more infra-red it radiates. How much given out or taken in depends on the surface of the object. For examples dark matt surfaces emits more radiation than light shiny surfaces even if there are at an equivalent temperature. Also, dark matt surfaces...
