Question

Why gases are bad conductor of heat even though they conduct heat by molecular momentum transfer?

Answer 1

Answer:

Air is a bad conductor because, to conduct heat current molecules should absorb heat and transmit it to neighbor by vibrating. ... So , "If air were a good conductor of heat" then soup will not stay hot for longer because this time convection+conduction will both help to transfer heat away from soup.
