Which is an example of conduction? a )soup is warmed in a microwave oven. b )a hand is burned when touching a pot handle. c )air above an ocean warms up and rises. d )a stone gets hot from sitting outside on a sunny day.

B )A hand is burned while touching a pot handle

B )A hand is burned when touching a pot handle.

Explanation:

When heat is transferred through the medium such that two object which are in contact with each other then due to temperature gradient the heat is transferred from hot object to cold object.

While in convection mode of heat transfer the thermal energy is transferred in such a way that the medium itself will move from one point to other point.

In radiation mode of heat transfer it is carried in electromagnetic wave form.

So here in this case we can say that heat transfer by conduction is followed by the direct contact of two objects.

so here correct answer will be

B )A hand is burned when touching a pot handle.

when we touch a hot pot handle then by direct contact heat is transferred to the hand
