Yes. The molecules of oxygen and nitrogen, when compressed, are closer together and the heat will transfer from one molecule to the next more easily than at normal pressure. It is wise to remember there is a danger that heating a vessel containing compressed air will increase the internal pressure even further, and may cause the vessel to rupture.

What are the significance of heat transfer during food processing?
Heat transfer kills necessary enzymes and destroys vitamins. The less heat the better.
Which is better a insulator or conductor to transfer heat?
By definition, a conductor.
Why does transfer of heat energy take place between objects?
Because transfer of heat requires particles, so solid objects will be better at conducting heat than gas.
What is convective heat transfer?
Convection heat transfer is the transfer of heat by the movement of a fluid.
Does silver transfer heat?
All metals tarnsfer heat well, and silver better than most, yes.
How can heat transfer be promoted?
Answer is within heat transfer equationconduction = (k.A.dT/x)dtConvection = (h.A.dT)dtRadiation = s.e.AdT4.dtIncrease of conductivity (k) or heat transfer coefficient (h) or area (A) or temperature difference (dT) or contact time (t) or emissivity (e) allow for higher amount of energy to transfer.Reduce of transfer distance (x) increase rate of energy transfer.Increase flow rate to boost convection heat transfer (fluid)Increase surface area of contact (solid - fluid)Design heat exchanger in counter current flow (fluid)Prolong retention time (higher contact time -> more heat can transfer)Change of heat transfer medium (better thermal conductor medium)Use of heat pump (promote higher temperature difference yield better heat transfer)Coat surface with black colour (higher emissivity promote radiation heat transfer)
What are two examples of heat transfer?
Convection - heat transfer through liquids.Conduction - heat transfer through solids.Radiation - heat transfer through vacuum.
Is lead a better conductor of heat than glass?
Yes, lead is a metallic solid, and therefore facilitates the transfer of heat (energy) better than other solids.
Who have the better heat transfer property?
Metals as silver, gold, copper have great thermal conductivity.
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.
