A thermos flask prevents heat loss through all three mechanisms by using a vacuum to stop conduction and convection and a reflective coating on the inner surfaces to minimize radiation, thereby maintaining the temperature of the contents.

Water in an electric kettle gets heated primarily due to conduction. The heating element transfers thermal energy directly to the water molecules upon contact. While convection and radiation may contribute minimally, the main mechanism responsible for heating water in an ...
The Sun’s heat reaches the Earth primarily through radiation. Radiation involves the transfer of heat energy through electromagnetic waves, such as light and infrared radiation, traveling through the vacuum of space.
In the method of heat transfer known as radiation, a medium is not necessary. Radiation involves the transfer of heat energy through electromagnetic waves, such as light and infrared radiation, that can travel through a vacuum, such as space. Unlike ...
The method of heat transmission in which the particles of the medium do not move is conduction. Conduction involves the transfer of heat through direct contact between particles in a material medium.
