How does insulated support in thermos flasks prevent heat loss?
Insulated support in thermos flasks prevent heat loss by creating a barrier that reduces heat transfer through conduction, convection, and radiation. The layer of insulation helps to trap the heat inside the flask, keeping the contents hot or cold for longer periods of time. This helps to maintain the temperature of the liquid inside the flask without allowing it to be affected by the surrounding environment.
Where Thermos flask prevent loss or gain of heat by a) Conduction b) Convection c) Radiation d) All of the ab?
d) All of the above. Thermos flasks are insulated to prevent heat transfer through conduction, convection, and radiation, keeping the contents either hot or cold for an extended period.
What were small bottles filled with smuggled hooch?
Small bottles filled with smuggled hooch were often referred to as "flasks" or "hip flasks". These bottles were discreetly carried to avoid detection during the Prohibition era, when the sale and consumption of alcohol were illegal in the United States.
Closed systems exchange energy but do not exchange?
Closed systems exchange energy with their surroundings in the form of heat or work, but do not exchange matter. This means that the total amount of mass in a closed system remains constant over time. Examples of closed systems include sealed containers and insulated thermos flasks.
What was needhams manipulated variable?
Needham manipulated the presence of air in his experimental flasks to test his hypothesis about spontaneous generation of organisms.
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.
What is a better material to use in a thermos flask?
Stainless steel is a popular material for thermos flasks because it is durable, has good insulating properties, and is easy to clean. Vacuum-insulated stainless steel thermos flasks can keep liquids hot or cold for long periods of time.

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
What is the uses of measuring cylinder filter flasks conical flasks round-bottomed flasks in the chemistry?
IS IS
What is the meaning of conical flasks?
There is no meaning of conical flasks. They have uses.
What are cryogenic flasks used for?
Cryogenic flasks are used to store and transport materials at very low temperatures, typically below -150°C. They are commonly used in scientific research, medical applications (such as storing biological samples and preserving vaccines), and in industries like pharmaceuticals and aerospace. The vacuum-insulated design of cryogenic flasks helps maintain the low temperatures for extended periods.
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.
Where can someone get cheap flasks?
A person can get cheap flasks at the nearby stores such as Wal-Mart, Target, K-Mart, and other stores like Staples. A person can also research where to find flasks and get them.
Why are beakers and flasks not used for heating solids?
the heat may not be distributed uniformly if solids are heated in beakers or flasks
What kinds of drinks are normally put in plastic flasks?
People can put alcoholic liquor drinks and wine in plastic flasks. You can also put water in plastic flasks as a drinkable liquid and carry them with you when you need it.
