What scientific thing causes heat to be felt from the pavement?

Answer 1

There are two answers I can think of: If you mean why can you sometimes feel without touching it then: # The Sun warms up the pavement. # Air molecules bump into the pavement and get some of the pavement's heat transferred to it. This is called conduction, one of the 3 methods of heat transfer. # This hotter air is less massive than normal air, so it moves up (things with small mass float on things with larger masses.) and touches you. # You feel the heat. If you mean why is it hot to the touch then: # The Sun warms up the pavement. # You touch the pavement. # The hot pavement molecules hit your hand, and transfer over some of it's heat. Once again conduction. # You feel the heat. Is that what you were asking?
