I cannot answer this question.
Heat transfer occurs when a kettle is placed on a lit gas ring, and the water is brought to the boil.
Conduction is the transfer of heat through direct contact.
The transfer of heat by fluid is convection.
No, in the universe radiation heat transfer is by far the largest transfer.
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).
correct
Heat transfer occurs when a kettle is placed on a lit gas ring, and the water is brought to the boil.
You have the mechanism of heat transfer correct but the name for it incorrect! The process where slow movements of mantle rocks transfer heat is known as convection.
the transfer of heat by currents within a liquid or gas
I think you might mean conduction.Conduction can transfer heat from one part of an object to another.We studied conduction in physics class.
Conduction is the transfer of heat through direct contact.
Convection heat transfer is the transfer of heat by the movement of a fluid.
Conduction is the transfer of heat between two parts of astationary system, caused by a temperature differencebetween the parts. Also,The transfer of heat energy by direct contact
Convection - heat transfer through liquids.Conduction - heat transfer through solids.Radiation - heat transfer through vacuum.
Convection heat transfer is the transfer of heat by the movement of a fluid.
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 is convection.
