WebThe Physics A thermos flask has double walls, which are evacuated and the vacuum bottle is silvered on the inside. The vacuum between the two walls prevents heat being transferred from the inside to the outside by conduction and convection. With very little air between the walls, there is almost no transfer of heat WebThermos flasks are able to keep a liquid hot (or cold) for long periods of time. The plastic stopper is a poor conductor, and so this will reduce the amount of heat transfer via …
