Why does plastic feel less cold/hot than glass or metal ?

Well, this is also equivalent to the old standby of a volume’s “total” heat versus measurement of its temperature, which is by definition a measure of some level of molecular energy at some level of near-instantaneous time (hedges so chemical physics and quantum guys can lob their grenades): a drop of hot bathwater, at some temperature, on your skin, vs a whole-body dunk in the whole tub of water at the same temperature.

Yes - but my point was merely to show that the two different materials really were at the same temperature, in spite of what our senses might tell us.
