Is air or fiberglass a better insulator?
Fiberglass is a better insulator than air because it has the ability to trap air pockets within its fibers, which reduces heat transfer. This makes fiberglass a more effective thermal insulator compared to the air itself.
Is gas or a vacuum a better insulator?
A vacuum is a better insulator than gas because there are no particles in a vacuum to transfer heat through conduction or convection. Gas molecules can transfer heat through conduction and convection, making them less effective as insulators compared to a vacuum.
Why is a vacuum a better insulator than air?
A vacuum is a better insulator than air because it lacks particles to conduct heat through conduction or convection. Without particles present, heat transfer is limited to radiation, which is less efficient. This makes vacuums good insulators for maintaining temperature, as they prevent heat loss or gain.
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 styrofoam a better insulator than wood?
Yes, styrofoam is a better insulator than wood because it has a lower thermal conductivity, meaning it is better at trapping heat and preventing it from escaping. Additionally, styrofoam is more resistant to moisture compared to wood, which can affect its insulating properties.

Is a material with a lower R-value a better insulator than a material with a high R-value?
No. A higher R-value is a better insulator.
How can you determine if foam is a better insulator than paper?
yes you can test it under a lamp and see the temp. for the foam and paper and if one has the lowest than that's the better insulator!good luck!
How does plastic act as a heat insulator?
For practical purposes, air is an excellent thermal insulator. So any material with lots of entrained air (and through which the air cannot freely pass) will be a good thermal insulator. The remaining conduction path through the material is along the filmy walls of the bubbles, and this path will be long and of small cross-section. A vacuum is of course a better thermal insulator, but there are practical difficulties in making a foam of vacuum bubbles. And there are some materials (some CFC gases) which are better thermal insulators than air, but once again there are difficulties in keeping these gases entrained in the foam bubbles.
Why does the glass on a window pane feel cooler to the touch than the wood frame surrounding the glass?
Wood is a better thermal insulator than glass, which is easily cooled.

Is a glass vacuum thermos vacuum better than a stainless steel vacuum?
Theoretically yes because glass is a poorer thermal conductor than steel.
Is cotton a better insulator than aluminium foil and tissue paper?
No, cotton is not a better insulator than aluminum foil and tissue paper. Aluminum foil is a good insulator as it reflects heat, while tissue paper acts as a thermal barrier. Cotton, on the other hand, is not as effective of an insulator because it does not have the same reflective or thermal barrier properties.
Why does a double glass window have argon?
Because argon is a better insulator than air
What material conductors electric current better than an insulator but not as well a conductor?
semiconductor
