The History Of The Vacuum Flask Company News News

2020-4-13  The vacuum flask was designed and invented by Scottish scientist Sir James Dewar in 1892 as a result of his research in the field of cryogenics and is sometimes called a Dewar flask in his honor. While performing experiments in determining the specific heat of the element palladium, Dewar made a brass chamber that he enclosed in another chamber to keep the palladium at its desired temperature.

Vacuum Flask Thermal Energy Transfer Revision Notes

Vacuum Flasks minimise thermal energy transfer. Conduction: The pockets of air around the middle of the flask which contains the liquid (the container) are poor conductors, because air is a poor conductor. The vacuum prevents conduction from occurring because there is no air (and therefore no atoms for these heat transfers to take place).
