How do vacuum flasks work?
think of it as a battery. it stores a large vacuum reserve while the engine is running. then its used whenever you use the device attached to it requiring the vacuum source. without it things like your heater and ac controls would not work properly because they require a large amount of vacuum to operate that your engine alone cannot supply fast enough.
What are the advantages of alchemy?
Gold Flasks Mount Stones Elixirs Transmutes Extended time for flasks These are just a few of the many advantages
In the adsorption of acetic acid by charcoal why are the flasks stopperd?
the flasks are stoppered to prevent evaporation of sample since the acetic acid is somewhat a volatile liquid
What is the space that has a pressure of zero pascals called?
Vacuum.
What is a boiling flasks proper name?
k Vacuum flask
Why does vacuum flasks silvered on the inside?
The motivation is to avoid heat transfer by thermal radiation.
How are non-vacuum flasks insulated?
To insulate a non-vacuum flask, a non- heat conducting material such as Styrofoam is put between the layers.
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.
How does vacuum flasks keep hot liquids hot and cold liquids cold?
by inhibiting heat conduction
What are the uses of a flask?
The round bottoms on these types of flasks allow more uniform heating and/or boiling of liquid. Thus, round-bottom flasks are used in a variety of applications where the contents are heated or boiled. Round-bottom flasks are usually used in distillation by chemists as distilling flasks and receiving flasks for the distillate One-neck round-bottom flasks are used as the distilling flasks in rotary evaporators.This flask shape is also more resistant to fracturing under vacuum, as a sphere more evenly distributes stress across its surface.
What is the purpose of a flask?
A flask is essentially a bottle. * In a labs, glass flasks (Erlenmeyer, Florence) are used for mixing heating and storing solutions. Sometimes they are graduated to show the volume of material that they contain.* Vacuum flasks are more robist, ususally with a side arm to remove gases * Insulated flasks keep things cold like liquid nitrogen
How do you insulated thermos?
Um......your question is worded oddly, but the way an thermos is insulated is by having a vacuum between it's two flasks. The vacuum causes heat transfer to reduce greatly.
Where can one go to purchase a vacuum flask?
Numerous stores sell vacuum flasks. One can purchase a vacuum flask at Walmart, Kmart, Sears, Home Depot, Lowe's, Target, Ace Hardware and many other places.
Which scientific principle allows vacuum flasks to work?
Heat energy, like light energy, can be reflected by some materials. ~MVMMS

How does the thermos maintain heat?
A real one is a vacuum flask (or better: two flasks with a vacuum between them) - and so the only heat loss is via radiation (except at the cap). But most today are simply foam insulation.
