There are three ways of heat transmission: radiation, convection and transmission. The silver cup in the stainless steel vacuum flask can reflect the radiation of hot water, the vacuum of the cup and the cup body can block the transfer of heat, and the bottle that is not easy to transfer heat can prevent heat convection. The thermos flask also applies the principle of magnetized water, which is to add magnets to the bottom and cap of the bottle to make the water magnetized.
