In any liquid.
Fluids i.e liquid and gas are poor conductors. Only convection is possible.
Conduction. The pan rests on the cooker top. Heat passes by direction conduction to the metal of the pan, and from the pan to the liquid.
no
no
Conduction takes place in liquids and gaz's
Liquid conduction
yes
yes
conduction and convection (which requires a circulation of the liquid).
yes. it is conduction on the surface to begin with. later on, it is convenction
Ions
Lack of a flow medium will inhibit conduction and convection.
