Method A is Convection

Method B is Conduction

Explanation:

From the problem, we can infer that method A is convection and method B is conduction.

Conduction, convection and radiation are the three main methods of heat transfer.

Conduction and convection requires material medium to propagate.
Radiation occurs in the absence of a material medium.
Conduction mostly occurs in solid. Here, heat is transferred from one hot end to the cold end of the solid. The vibration of the particles in the hot end causes the transfer of kinetic energy to the cold end until thermal equilibrium is reached.
In convection, heat is primarily transferred in fluids as a result of density differences. Convection involves the motion of the materials of the medium. Hot air is light and it rises whereas cold air is dense and it sinks.
