Let say we have a piece of aluminium that is 200 C and a piece of steel that is also 200 C and we put them each in a equally sized 2x2 meter room with equal tempI'm guessing the air in the room with the aluminium will get heated faster due to it's higher thermal conductivity or am I wrong?Will the air in the room with the steel be warmer longer, but wont reach higher temp compared to the other room?
You are wrongThe heat is passed from the metal to the air via convection not via conduction within the metalNow Aluminium is not as dense as steel so that a block of the same size will not hold as much heatBut it has a higher specific heat so that a block of the same mass will hold more heat than the steelThe amount of heat determines the final temperature of the roomThe rate of heating is more dependent upon the nature of the surface ( rough or smooth, large or small area) and the shape which affects the speed of the air movement( fast moving air shifts more heat more quickly than slow moving air)
