How do you reduce unwanted energy transfers
WebAug 27, 2024 · Insulation works by slowing the transfer of heat, which can move in three ways: conduction, convection, and radiation. Do insulators stop energy transfers? There is air or an even better insulator such as argon gas between the two panes of glass. This reduces energy transfer by conduction.
