Are diapers good insulators?
diapers are good insulators because they hold in the cold and and heat but is a bad conductor
Are towels good insulators?
Yes they are.
Are train tracks conductors or insulators?
The rails are good conductors The wooden ties they rest on are insulators
Are materials containing air usually good insulators?

What is in an example of a good insulator?
A material or an object that does not easily allow heat, electricity, light, or sound to pass through it. Air, cloth and rubber are good electrical insulators; feathers and wool make good thermal insulators.
What are some good insulators for a thermos?
spongespaper towelglassduck tapesawdustmetals...these are excellent insulators.....
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.
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
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 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 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.
What kinds of materials make good insulators?
There are a number of materials that make good thermal insulators. Blankets and pockets of air make good thermal insulators for example.
What are some good insulators?
plastic, paper, wood, cardboard, and rubber are all good insulators
What are good food insulators?
I would guess that a vacuum thermos would be the best device to insulate a consumable liquid. The area of vacuum prevents heat loss or gain through conduction, and convection. I don't know how well it does to prevent radiation. I would think that prevention heat loss or gain through radiation would depend on what the material was made of. Also, if you keep the cap on the thermos as much as possible, it helps prevent heat loss or gain. Try to find the episode of Good Eats where Alton Brown talks about making sauces. I think I is hollandaise sauce that he talks about putting in a thermos and goes on to discuss how thermoses work.
