When I have a metal object at 0 degrees and a plastic object at 0 degrees, the metal feels colder as heat is conducted away at a faster rate. The reason for that would be that the metal is a better conductor of heat so when my hand touches it, it can start vibrating more quickly than the plastic.
So does this mean that how fast heat gets conducted into another material depends on the warmer material? For example if the metal and plastic is at 60 degrees, when I touch them they should feel the same? Because now that heat is transferred to the hands, the rate of heat flow into the hand from the hotter object will be the same (since the kinetic energy of the metal and plastic particles is the same so they should have the same rate of heat transfer to the hand). Is this correct?
Thanks
