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 does heat transfer by radiation conduction and convection?
a thermos limits heat transfer through the walls of the thermos. that lets the fluid inside the thermos keeps its temperature nearly constant for a long period of time (whether the temperature is hot or cold).
How does a flask keep hot liquid hot?
There are several types of flasks. They are all containers or vessels, usually designed to carry a liquid and often made of glass. They sometimes have a cap and are narrower at the top, but usually do not have a handle.The first distinction is flasks that are used in a laboratory. There are several types, including erlenmeyer flasks, florence flasks, round bottom flasks, distilling flasks, volumetric flasks, and others. A description of each one is listed to the left under the Related Questions links.Another type of flask is instead used to carry alcohol. It is a small container usually shaped to fit in a back pocket. It can hold any liquid but usually was designed for alcohol.See the Related Questions and Web Links to the left for more information and pictures of different types of flasks.
Is manometer used to measure the pressure of liquid?
yes,manometer is an instrument . It is used to measure pressure of liquid.
Could you please use the science word thermos in a sentence?
They kept the liquid nitrogen in a thermos so it stayed cold. They used a thermos of oil to keep the sodium from contacting air and water.
What is a thermos bottle made out of?
Traditionally, Thermos bottles used borosilicate glass for the vacuum insulator, with a plastic or metal envelope. Modern Thermoses are typically made entirely of steel.
What did a thermos used to be?
Long Johns for pants thermos but I dont know what the shirts are called.
Is it safe to store liquid nitrogen in an ordinary household thermos?
Old glass thermoses are very similar to dewars used in chemistry for carrying liquid nitrogen.A glass thermos would be safe for transporting and temporary storage of liquid nitrogen.However, it would not be recommended to seal the top tightly with the stopper as the liquid nitrogen will slowly evaporate and pressure could build up inside the 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.
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 the main reason stainless thermos bottles should not be washed in a dishwasher?
A dishwasher will ruin the finish on the outside of a stainless thermos bottle, making the outside unsightly. As far as durability goes, if the thermos bottle contains a vacuum seal, washing in the dishwasher will cause the seal to malfunction and the thermos will begin to leak.
What does antifreeze liquid do?

Why does thermos bottles advertised as good for 24 hours while others are claimed to be able to keep liquids hot or cold for 48 hours?
The claim of 24 hours versus 48 hours typically depends on the insulation quality and thickness of the materials used in the thermos bottle. Thicker insulation and higher-quality materials can help a bottle retain temperature for a longer period. Different designs and technologies might also impact how long a bottle can keep liquids hot or cold.
What is the reason you have thermos?
well mostly because we might have packed a lunch and wanted to bring something that had to stay warm. Thermos are used to keep your food warm
Where was the thermos derived from?
The thermos was derived from the invention of a vacuum flask by Sir James Dewar in the 1890s. The vacuum insulation technology used in the thermos helps to keep liquids either hot or cold for extended periods of time.
A glass or plastic container which is normally used for storing liquid?
