Best Answer

Some Materials conduct heat more than others for example if you poured hot water on a metal pole the pole would become hot much faster than if you poured the hot water on a plastic pole. Coffee Flasks use materials that conduct heat the least so that not much of the heat is able to pass through it.

In a decent flask that is preheated with boiling water before the hot beverage is put it, the coffee should stay hot for about eight hours.

Only some coffee makers come with a hot pad to keep your coffee warm, however you can also buy your own hot pad if your maker doesn't come with one.

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.

How does thermos flask maintain the temperature of the object inside it?

The flask makes use of heavy insulation, either by vaccum, air cushion or just filled with very poor heat conductors to slow the heat loss from a hot drink or warming from the enviroment.


Why your vacuum flask cannot maintain the cold anymore?

There could be a crack or leakage that allows air to flow in or out of the flask. It may be time to replace the flask with a new one.


How do you get an egg out of a flask?

you heat the bottom of the flask. as temperature goes up, the volume will go down and push the egg out.


What is a calibrated mark on a measuring flask?

This mark is the indication of the exact volume of the flask at a given temperature (generally at 20 0C).


What Vacuum flask keeps liquid at same temperature?

There is no way to permanently store heat. The most you can expect, from a high-quality vacuum flask, is to keep the liquid cold, or hot, for a fairly long time. But gradually, some heat will seep in, or out, until the temperature in the vacuum flask will be equal to the temperature of the surroundings.


How do you keep water hot?

A Thermos/vacuum flask is probably the best for small volumes of hot water (1 - 2 pints) After that any receptacle that is well insulated will maintain the temperature for a limited time.


What is a good insolater?

a flask is an insolator because if you have coffee,tea or juic it keeps it hot and cold


How does a vacuum flask reduce heat loss from a hot liquid inside?

Due to open space isolating the flask from external temperature


What is the scientific principle of making thermos flask?

thermos flask actually works on the principle of insulator. air is trapped between 2 walls of the flask. air being a bad conductor of heat traps it between the walls. this keeps the material in the flask hot for a longer period.add. Actually, usually there is a vacuum between the two walls of the flask, for this is a better insulator than air. hence the name 'vacuum flask'.


A flask with a capacity of 1.00dm contains 5.00g of ethane The flask will burst if the pressure exceeds 1.00x10 Pa at what temperature will the pressure of the gas exceed the bursting temperature?

See the Related Question to the left for how to solve Ideal Gas Law Problems so as to determine at what temperature to keep the flask so that the pressure is below the specified value.
