How does a vacuum flask keep tea hot?

Method for preparation of 1 normal sulfuric acid?
normality of A = #gram equivalent weights A divided by #litres of solutionthus: measure a gram equivalent of H2SO4 (49g) and add to 1000ml volumetric flask that has 500ml deionized distilled H2O. stopper flask, mix by swirling, open flask and fill to 1000ml mark, thoroughly mixOR1N H2SO4 = 0.5M H2SO4volumetrically measure 500ml 1M H2SO4volumetrically transfer to 1000ml volumetric flask (using DDH2O)fill to 1000ml mark with DDH2O
How do flasks keep drinks hot?
because conduction,convection and radiation keep the flask thermal because of what they do
What can be held in a thermos flask?
Hot drinks such as tea and coffee are usually held in a thermos flask. The flask will keep the drink warm for several hours when one is outside or on the move. Cold drinks can also be kept in them or even non drinking liquids that one wishes to keep at a steady temperature.
What is a Flat Bottomed Flask and what is it used for?
Flat bottomed flasks are used for the same purposes as round bottomed flasks. The differences are: 1. the flat bottomed flask can stand alone, is more robust but not specifically designed to withstand open flames. 2. the round bottomed flask, also called a Florence or boiling flask, can withstand open flame for long periods, allows for more even heating of its contents, facilitates swirling, and requires supporting apparatus since it cannot stand alone on its spherical bottom.
What is the name of the thing used to keep liquids warm or cold?
Vacuum flask.
What is A container to keep drinks cold?
