One dimensional heat transfer is when the temperature varition is in one direction only while two dimensional heat transfer is when temperature varies mainly in two directions (i.e x,y or r,z).

How does transient heat transfer differ from steady state heat transfer?
In transient heat transfer, the rate of heat transfer is changing with time. By definition, in steady-state heat transfer, the rate of heat transfer does NOT change with time. In the real world, heat transfer starts out as transient and then approaches steady-state with time until the difference between the actual and the ideal becomes negligible or until thermal equilibrium is approached.
Two objects have the same total thermal energy They are different sizes Are they at the same temperature?
No, there will only be a spontaneous transfer of heat if the objects are at different tempratures.No, there will only be a spontaneous transfer of heat if the objects are at different tempratures.No, there will only be a spontaneous transfer of heat if the objects are at different tempratures.No, there will only be a spontaneous transfer of heat if the objects are at different tempratures.
What are 3 ways heat is produced?
Conduction, convection and radiation TRANSFER heat; you can't create heat; the law of conservation of energy states that energy cannot be created or destroyed. Therefore, you can't create heat.
The transfer of heat by fluid?
The transfer of heat by fluid is convection.
Is convection the main type of heat transfer?
No, in the universe radiation heat transfer is by far the largest transfer.
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.
Which layer of earth is mostly iron but split into two parts that differ in physical state and primary method of heat transfer?
The Core, (Barysphere).

The transfer of heat by means of rays?
Radiation is the means of heat conduction through electromagnetic (EM) waves. These waves are known as Thermal radiation and differ from other EM waves as Radio waves, Microwaves etc. The other two methods of heat transfer are Conduction and Convection where both require a medium (such as air, water etc.) for the transfer to take place.

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 is convective heat?
Convection heat transfer is the transfer of heat by the movement of a fluid.
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
