Why a vacuum between a panes is better than air?
How would you fit a vacuum between window apnes :) Jokes aside, neither heat nor cold can pass through a vacuum, so you can't lose or gain heat. There's nothing there to transport the thermal energy, whereas in air, there is.
Is fibreglass a better insulator than vacuum?
No. If you can get it, vacuum is the best insulator.
Why is there a layer of air in between windows?
It's not air - it's Argon gas. Argon gas is an inert gas, and a poor heat conductor - which is why double-glazed windows keep the heat in better than single-glazed panes.
Is pressure cleaning better than vacuum?
In my opinion Pressure Cleaning is definitely better than vacuuming. With pressure cleaning it gets rite into the surface and sanitises, and does not realease dust particles into the atmosphere.
How double glazing is a good insulator?
The big insulating value of double glazing has to do with the space between the two panes of glass. If it's filled with air, that's good, because air is a poor conductor of heat. For even greater insulating value, the space between the panes can be filled with argon gas instead of air. Argon is an even worse conductor of heat than air is.

What characteristics made the transistor better than the vacuum tube?
There were obvious differences between the trasisitor and the vacum tube. The transistor was faster, more reliable, smaller, and much cheaper to build than a vacuum tube. One transmisor was the equivalent 40 vacuum tubes. They also didn't produce heat compare it to a vacuum tubes. Conduct electricity faster and better than vacuum tubes.
Is a glass vacuum thermos vacuum better than a stainless steel vacuum?
Theoretically yes because glass is a poorer thermal conductor than steel.

How can you tell the difference between Scott 731 and 767?
Multiple 25-stamp panes were printed on a single large sheet and then cut into individual commemorative panes. The spacing (gutters) between the 767 panes is noticeably lager than between those on the 731 sheet. However, once they are cut, it is almost impossible to tell which is which. For that reason, many collectors collect "gutter blocks" of the 766 and 767 issues rather than the full panes. A gutter block has the corner stamps from 4 panes of the large sheet, showing the wider gutters in the form of a cross between them. (It looks like 4 houses sitting on the corners of two wide intersecting streets.) EBay, among other sources, often has gutter blocks listed.
Will bed bug eggs die in a vacuum?
In a total vacuum I am sure they would die off. A vacuum cleaner will not kill them off but it is better to have them there than in the bed.
Are upright vacuum cleaners more efficent?
"Not necessarily, an upright vacuum can be more efficient but depending on the type or price it may not be. Some of the other types can do better than an upright vacuum, and an upright vacuum can be more efficient than others it mainly depends on the suction power or how old the vacuum is."
Can vacuum cleaner be suitable to clean ceiling fans?
Depends on the type of vacuum cleaner. The Dyson works a lot better than the Shark does.
Is a normal vacuum cleaner better than one that moves on its own?
Yes, you can do the work yourself. With a mechanical vacuum that does the work for you, you are not going to get nearly as good of a clean that a regular vacuum gets.
Why there is mist on the window?
If the moisture is on the inside surface than the humidity inside your home is high. If it is in between the 2 panes of glass in an insulated unit than the seal has failed and the ig needs to be replaced.
Why does a vacuum pack preserve food better?
Vacuum packaging preserves food better than some other methods because it removes the oxygen from the packaging; without oxygen, bacteria and mold cannot survive.
