What else can I help you with?
Why are the walls of the vacuum flask made from glass?
Glass is a good insulator, helping to maintain the temperature inside the vacuum flask. It is also transparent, allowing users to see the contents of the flask easily. Glass is also odorless and does not affect the taste of the liquids stored inside.
Why is the inside of a thermos flask silver?
The inside of a thermos flask is often silver because silver is a good reflector of heat. This helps to reduce heat transfer by reflecting heat back into the flask, keeping the contents hot or cold for longer periods of time.
Is a plastic bag a good conductor?
No, because plastic is an insulator making it a very bad conductor of heat.
Is CaSO4 a good conductor?
No, CaSO4 (calcium sulfate) is not a good conductor of electricity. It is an insulator.
Why is a tharmos flask good at keeping drinks cold as well as hot?
A thermos flask is good at keeping drinks cold or hot due to its vacuum-insulated design, which minimizes heat transfer by conduction, convection, and radiation. This design creates a barrier that reduces the exchange of heat with the external environment, helping to maintain the temperature of the liquid inside for an extended period of time.
Must a flask be a good conductor of heat?
No, a flask does not necessarily have to be a good conductor of heat. In fact, many flasks are designed with insulating materials to help maintain the temperature of the liquid inside, whether hot or cold. So, a flask can be effective at keeping beverages hot or cold without being a good conductor of heat.
Why the flask is having a silver coating in the inner surface?
The silver coating on the inner surface of a flask helps to reflect thermal radiation, keeping liquids either hot or cold for longer periods of time. This coating also adds durability and resistance to corrosion, improving the longevity of the flask. Additionally, silver is a good conductor of heat, which helps to maintain the temperature of the liquid inside the flask.
What are the property of good conductor?
a good conductor should be electrically neutral.
Why are the walls of the vacuum flask made from glass?
Glass is a good insulator, helping to maintain the temperature inside the vacuum flask. It is also transparent, allowing users to see the contents of the flask easily. Glass is also odorless and does not affect the taste of the liquids stored inside.
Why is the inside of a thermos flask silver?
The inside of a thermos flask is often silver because silver is a good reflector of heat. This helps to reduce heat transfer by reflecting heat back into the flask, keeping the contents hot or cold for longer periods of time.
Can a static magnetic field exist in a good conductor?
A static magnetic field can exist in a good conductor. When the conductor carries current, it produces the flux which can exist inside the conductor. Due to this flux, magnetic field and intensity at a point inside the good conductor.
Is Erlenmeyer flask good of heated solid?
The Erlenmeyer flask is not good for heating solids.
What are properties of good conductors?
a good conductor should be electrically neutral.
Is neptunium a good or poor conductor of heat and electricity?
as it is a metal it should be an excellent conductor of both.
What characteristic does a good conductor possess?
A good conductor should have strong communication skills to effectively convey direction and feedback to musicians. They should also have a deep understanding of music theory and interpretation to bring out the best in performances. Lastly, a good conductor should have excellent leadership skills to inspire and motivate the ensemble.
What is the main cause of heat loss in a normal thermos flask?
The main heat loss in a good thermos flask, is due to heat conducted through the material. (Glass or Stainless Steel). There should be little heat lost through the vacuum of the flask.
What do the inner walls of a vaucum flask silver coating?
The inner walls of a vacuum flask are coated with a layer of silver to minimize heat transfer by reflecting thermal radiation back into the flask, thus helping to maintain the temperature of the contents inside for longer periods of time. Silver is a good reflector of thermal radiation and helps to reduce heat loss through conduction and convection within the flask.
