Is a mug a bad heat insulator?
No, a mug is not a bad insulator. Most mugs are made from materials like ceramic or glass, which are good at retaining heat. However, the effectiveness of a mug as an insulator may vary depending on the material and thickness of the mug.
How does an insulator reflective surfice vacuum and the bottom insulator work in a thermos?
In a thermos, the reflective surface on the inner side of the vacuum chamber reflects back the radiant heat, reducing heat transfer between the hot or cold content and the environment. The vacuum between the inner and outer layers acts as an insulator by preventing heat transfer through conduction and convection. The bottom insulator helps to further minimize heat transfer by providing an additional barrier against heat loss or gain through contact with external surfaces.
How is conduction prevented in a thermos flask?
Conduction is prevented in a thermos flask through the use of a vacuum layer between the inner and outer walls of the flask. The vacuum layer acts as an insulator, reducing heat transfer by conduction. Additionally, the walls of the thermos flask are usually made of materials with low thermal conductivity, further minimizing heat transfer through conduction.
How does a plastic stopper in a thermos bottle control heat transfer?
A plastic stopper in a thermos bottle helps to control heat transfer by minimizing conduction through the opening, where heat can escape or enter. The plastic acts as an insulator, reducing heat loss or gain from the contents inside the thermos. This helps to maintain the temperature of the liquid for a longer period.
How do thermos work?
Thermoses work by using a vacuum-sealed double-wall construction to minimize heat transfer by conduction, convection, and radiation. This helps to keep hot liquids hot and cold liquids cold for an extended period of time by reducing heat loss or gain from the surrounding environment. The vacuum insulation prevents the transfer of heat, while the double-wall construction adds an extra layer of protection.
Is thermos a conductor or insulator?
you tell me if you fill a thermos with hot soup or hot chocolate put the lid on and then touch it is it hot or cold. odds are it is warm so it is hard to say. but the thermos is an insulator

What is the difference between a heat insulator and elctrical insulator?
an electrical insulator blocks the flow of electricity (like the rubber around power cords that stop you from getting electrecuted) and a heat insulator block the flow of heat (like a thermos)
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.

How is a thermos made?
a themos is made in many parts. A first coat a insulator then the inside coat is filled with a substance called foam tissue a material that finds the mold of its insulator
What is a good insulator for heat?
Either a vacuum (thermos bottle) or air that can't move ... which is just what foam insulation is (tiny bubbles).

Thermos bottles are used to keep liquid what?
Thermos bottles are generally used to keep liquid from changing temperature for a longer period of time. Usually, one pours hot liquid into the bottle, and it will remain warm for longer, but they are also effective at keeping cold liquid cool.
