I just thought about the following case and I have a doubt. Say I have a system like this : B-------A-------B' where A is a continuously heated metal so that it's temperature remains constant with time. Imagine there's a fluid like air between A, B and B' so that A transfers heat to B and B' via convection. Suppose that the temperature of B is almost the one of A and the temperature of B' is much lower than the one of A. Suppose also that B and B' don't transfer heat to each other (because they are too far from each other). Last supposition : B and B' are the same material, say a metal (whose specific heat is a constant). My question is : If B get heated by 1K, does B' also get heated by 1K? I was tempted to say yes because they have the same specific heat but now I have doubts. I think that maybe B' can be heated more than 1K while B got heated by 1K, because the temperature of B is closer to the one of A than the one of B' is. Maybe I should write down some equations, but I'll soon learn about gradient in cases similar to this one. Thanks in advance.
