How would heat transfer occur in the following substances or objects?
the atmosphere
How would it be possible that there could be high temperature but no heat transfer?
Heat transfer will only occur if there is a difference in temperatures. So if an object is high temperature but the surrounding area is also high temperature there will be no heat transfer.
Heat is the transfer of thermal energy because of difference?
Heat is not the transfer of thermal energy. Heat is the thermal energy. What drives itacross a boundary between substances or objects is a difference in their temperatures.
Thermal energy transferred between objects which have different temperature?
A transfer of heat (H) energy does not occur without a temperature differential. If the two objects had different amounts of H then a transfer would indeed occur. In this case heat would flow from a higher to lower temperature object.
Does the difference in the level of heat between two substances determine the heat transfer rate between the substances?
true

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.

true
Can oxygen conduct heat?
All substances, including oxygen, conduct heat. Oxygen, though, is a poor conductor of heat. Since it is a gas at room temperature it will transfer heat primarily by convection.
At room temperature a filled floor will feel cooler to the bare feet compared to a wooden floor why?
Heat sink, insulative value of air, density of substances & heat transfer.
How do you explain the difference between conduction convection or radiation can transfer heat explain?
It's a different way to transfer heat. One object emits electromagnetic radiation (for example, infrared - though it depends on the temperature); another object absorbs it. Heat transfer through radiation can occur in empty space; with conduction and convection, that's not possible.
Why must substances be touching in order for conduction occur?
Because, conduction is the transfer of heat flow fro one object to another. So that means they must touch to make conduction occur.
Why does cooling occur when evaporation takes place?
I think in general,heat is transfer from system to surrounding ,and naturally temperature decrease and it cooled
How do we know when the transfer of heat has ended?
It is when all bodies are at the same temperature.
