1892
Who invented the thermos?
The thermos was invented by Sir James Dewar in 1892. He developed the vacuum flask, which is now commonly known as a thermos, to keep liquids hot or cold for extended periods of time by minimizing heat transfer through a vacuum-sealed container.
When did sir James dewar invent the thermos flask?
Sir James Dewar invented the vacuum flask, commonly known as the thermos, in 1892. Dewar's design revolutionized the way liquids could be stored and kept at a stable temperature for long periods of time. It was a significant contribution to the field of insulation and preservation of temperature-sensitive materials.

Who create a thermos?
This is from wikipedia:The vacuum flask was invented by Scottish physicist and chemist Sir James Dewar in 1892 and is sometimes referred to as a Dewar flask after its inventor. The first vacuum flasks for commercial use were made in 1904 when a German company, Thermos GmbH, was formed. Thermos, their trademark for their flasks, remains a registered trademark in some countries but was declared a genericized trademark in the U.S. in 1963 as it is colloquially synonymous with vacuum flasks in general.
Substance that contains the vacuum in a vacuum flask?
Glass
What is vacuum cup?
it is the cup that comes on a vacuum flask
How does a themos flask work?
Also known as a Buchner or vacuum flask, the flask uses vacuum to filter samples. A vacuum hose is attached to the hose barb and the funnel is placed on top. As the hose creates a vacuum, the sample is filtered through the funnel.
Vacuum is mantained in thermos flask?
A vacuum is maintained in a thermos flask in order to prevent heat transfer by conduction and convection. The absence of air molecules in the vacuum reduces the amount of heat that can be transferred through these processes, helping to keep the contents of the flask hot or cold for longer periods of time.
