What else can I help you with?
How do you make a thermos without a vacuum that prevents heat?
Insulate the thermos with a very low heat-conducting material. Low density objects such as ceramic or foam are typically good insulators.
What 3 insulators that can be used in a thermos bottle?
Heat, cold, pollution
Which type of container keeps liquid hotter for more time?
the answer is a Thermos because it is made with insulators.
What are some good insulators?
plastic, paper, wood, cardboard, and rubber are all good insulators
How thermos flask works to keep thing hot or cool?
Thermos jugs are just very good insulators. Just like your house, they're designed to keep one or the other of extreme temperatures away from the inside of the jug ...and vice versa. FriPilot
What are good thermos insulators?
Good thermos insulators typically include materials like vacuum-sealed glass, stainless steel, and foam. Vacuum insulation is particularly effective as it eliminates air between layers, reducing heat transfer. Additionally, materials like neoprene and rubber are used in external layers to provide further insulation and protection. These materials help maintain the temperature of the contents, keeping liquids hot or cold for extended periods.
Is a thermos good after 20 years?
Can be, if the vacuum is good. In glass thermos if the glass is not broken it is okay. In steel thermos if the vacuum has not been lost it will be. You can test a steel thermos by simply filling it with boiling water, if the outside of the thermos becomes hot the vacuum has been lost and one will need a new thermos.
What causes some materials to be good insulators of electrcity?
O
What feature of a thermos does not limit heat flow?
Vacuum insulation is a feature of a thermos that does not limit heat flow. By creating a vacuum between the inner and outer walls of the thermos, heat transfer through conduction and convection is minimized, allowing liquids to maintain their temperature for longer periods.
How and where does the most heat loss occur in a thermos bottle?
The most heat loss in a thermos bottle occurs through conduction, convection, and radiation. It mainly happens at the opening of the thermos bottle where there is direct contact with the surrounding environment, as well as through the materials used in the construction of the bottle that are not efficient insulators.
Why some thermos bottles are good for 24 hours but others are for 48 hours?
A thermos is only good because of the material it is made with. A thicker material will keep whatever is inside cold or warm longer.
Why are plastic good electricity insulators?
Plastics are a good electrical insulators because they are insulators. Electricity could not pass through them unlike copper. Another good example of insulators is rubber.
