What are some good science experiments that are in the 6th grade science book?
What is the difference in the hardness between glass and fiber glass
How does heat transfer by radiation conduction and convection?
a thermos limits heat transfer through the walls of the thermos. that lets the fluid inside the thermos keeps its temperature nearly constant for a long period of time (whether the temperature is hot or cold).
Name the foods that a person should eat to prevent constipation?
Foods that are good for preventing constipation are goods that are high in fiber. Broccoli and prunes are both good for preventing constipation.
What happens if you don't recycle metal?
By not recycling you are putting your health and other peoples health in danger too.. the chemicals get into our body and we will die if people litter every day
Why is a thermos flask good at keeping drinks cold as well as hot?
Because it has good insulation so it prevents boss loss and gain of heat from the surrounding ---- Well that's true, but more interestingly, it has a glass chamber inside which is smaller than the outer casing. The air between the glass chamber and the outer casing has had almost all of the air removed, and is therefore a vacuum. This makes the heat unable to escape between the inner chamber and the outer casing, keeping the liquid hot. It also stops heat from outside being able to get into the liquid stored in the glass chamber, therefore keeping it cold. Most of the heat from the flask is lost from the lid, since the liquid has to come out of somewhere.
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.
Make a sentence with the word fiber glass?
Fiber glass is a synthetic building material. It is really made of glass, but is processed in such a way as to be strong, light weight, and durable.My tennis raquet is made of fiber glass. Speed boats made of fiber glass really go fast. Fiber glass makes good insulation.
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.
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.
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.
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.
Is fiber glass a good shock absorber?
Yes it is.
Why is fiberglass a good insulator?
A: Glass is a very good insulator and fiber glass are just fibers of glass. VERY dangerous if inhaled because of it.
What are optical fibers made of?
Good optical fiber is made of glass, but inexpensive fiber is sometimes made of plastic.
Can you use fiber glass on a car?
Yes you can use it fibre glass looks good on a car
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.
