Why is fibreglass a good insulator?
cause its the insulation they use to heat your home; usually found in walls
The transfer of heat by fluid?
The transfer of heat by fluid is convection.
Why is fiberglass a good heat insulator?
materials such as fibreglass are good insulators because they contain pockets of trapped air. :)
Is convection the main type of heat transfer?
No, in the universe radiation heat transfer is by far the largest transfer.
Is conduction a heat transfer by direct contact of particles of matter?
Yes, whereas convection heat transfer is the transfer of heat via a liquid, and radiative heat transfer occurs through empty space (like the heat you feel from the sun).
Why apply insulation foam?
To improve insulation against heat or cold. Insulating foam is more efficient than fibreglass batts.
What is convective heat transfer?
Convection heat transfer is the transfer of heat by the movement of a fluid.
What are two examples of heat transfer?
Convection - heat transfer through liquids.Conduction - heat transfer through solids.Radiation - heat transfer through vacuum.

What is convective heat?
Convection heat transfer is the transfer of heat by the movement of a fluid.
How does temperature affect the rate of heat transfer?
For conductive and convective heat transfer, the rate of heat transfer is proportional to the the temperature difference; if you double the difference you will double the rate of heat transfer. For radiative heat transfer, the rate of heat transfer is proportional to the difference of the 4th powers of the absolute temperatures.
The transfer of heat by fluid?
The transfer of heat by fluid is convection.
What do conduction and convection have in common?
They're both modes of heat transfer via material media.
Winds transfer heat energy by what method of heat transfer?
convection
How heat transfer is controlled?
There is a special mechanism that controls heat transfer.
