A vacuum bottle has a double walled silver bottle with the air removed from the space between the walls.?
describe how this design keeps food hot or cold by dealing with conduction, convection, and radiation.
Heat leaves a bottle either through Convection, Radiation or Conduction.
With the vacume, you eliminate Convection and Conduction, because there is no air for the convection and the inner suface is in contact with the outer surface, and therefore no Conduction. The Silver Bottle reflects that radiation and preserves the heat even more efficiently.
I hope you understood and thanks for making me revise my science class information.
