They are used to keep hot liquids warm because they are an insulator they're thick and will keep the heat in the liquid longer than just a cup as well they are used because of there coffee cup lid which makes it easy to take with you onto a job site or just anywhere really.

Which type of container keep liquid hotter longer?
If you are using wood, metal, plastic, or a thermos it would have to be a thermos because inside of it there insulators. Insulators are used to keep whatever is inside the same without the stuff outside interfering. Why else do you think we drink hot coffee in a thermos.
What did Sir James Dewar use the thermos for?
He didn't. He used a Dewar or vacuum flask. It is used to keep things hotter or colder than the surrounding ambient temperature. He failed to patent the idea and it was subsequently patented by Thermos. Thermos is still a registered trade mark in many countries, though it has been declared generic in the US.
What is the use of florence flask in laboratory?
The Florence Flask is used for heating subtances that need to be heated evenly. The bulbed bottom allows the heat to distribute through the liquid more evenly. The Florence Flask is mostly used in distillation experiments.
Why does the hot tea in a Thermos flask remain hot for a long time?
The Thermos (vacuum) flask has a double skinned glass cylinder inside. Between the two walls of the glass cylinder is a vacuum. The glass cylinder is also silvered on all inner and outer surfaces. Both the vacuum and the silvering help to prevent the rapid cooling of a hot liquid, or the warming of a cold liquid. The vacuum inhibits heat transfer by conduction. The silvering reflects the heat and inhibits the heat escaping from the flask. Thermos (often used for a vacuum flask) is a trade-name.Eventually, as anyone who uses a vacuum flask, the once hot drink will have become cool by the end of the day.
What unit of measurement does a Beaker or Erlenmeyer flask use?
Milliliters, sometimes liters
What is flask and how is it used?
A flask is basically a thermos that is used to hold liquids (beverages) that are meant to be kept warm.
What is the name of the thing used to keep liquids warm or cold?
Vacuum flask.
What is the thermo flask?
Thermos flask is a thermos container used to store liquids like any hot drink. The liquid added to thermos flask will retain the temperature even after some time irrespective of external temperatures.
Use of flask?
A flask is a container for liquids. It is similar to a bottle.
What is a Flat bottomed Flask and how is it used?
It's a flask with a flat bottom. It's used for containing liquids when you don't want to have to use a stand to keep it from tipping over.

How does thermoflask work?
Thermos Flask is a container that is used to prolong the temperature of a liquid. If a liquid it is hot,the thermos flask will work to make it stay hot longer. The heat will have no way to escape the flask which means the heat will stat longer, causing the liquid to stay hot longer.

What is a E flask used for?
The Erlenmeyer flask is used for titrations, to contain the solution from a filtration, to contain liquids, to make chemical reactions etc.
What is the function of a bottom flask?
It is used to heat liquids or to made chemical reactions.
