What can slow the movement of heat energy from a warmer object to a cooler object?
Transfer of heat can be slow down by increase insulation. For radiation heat transfer, colour coating could reduce rate of radiation in the same manner as insulation. Reduce surface area of heat transfer (or area of contact) can also reduce rate of heat transfer.
How can heat transfer in liquids and gases be reduced?
Insulation will reduce heat transfer.
How is the average rate of heat transfer calculated?
when is heat transferred?
How does fleece reduce heat transfer by conduction and convection?
it reflects the heat back
How does a thermos reduce heat transfer using convection?
A thermos reduces does not reduce heat transfer using convection, it reduces heat transfer BY convection. This is because there is a vacuum between the container of the liquid and the outer shell off the thermos. This means that no fluid will go round the inside conducting heat one way or the other. Hope this helped

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.
What does an insulator do to the rate of heat transfer?
It reduces the rate of transfer.
How can heat transfer in liquids and gases be reduced?
Insulation will reduce heat transfer.
What is the heat which travel molecule to molecule?
if you mean the transfer rate of heat ?; the heat transfer rate depends on the atom or molecule type .
How is the average rate of heat transfer calculated?
when is heat transferred?
How does fleece reduce heat transfer by conduction and convection?

Does temperature difference does not affect heat transfer rate?
yes

Why does closing windows reduce heat transfer?
because it doesnt allow heat to get inside or outside, depending on the season
How does a vacuum bottle keep food hot or cold?
The main idea is to reduce the heat transfer out of the vacuum bottle, or into it. A vacuum greatly reduces the transfer of heat by conduction and convection, while the mirror reduces heat transfer by radiation.
Why do different materials heat up at different rate?
usually metals or conductors get the heat energy from the heat. the heat transfer the particles in the conductors which causes it to heat up in a faster rate to get it hot.
