That's heat transfer by the process of conduction.
The stuff in the pot heats uniformly because of convection.
That would be conduction. Metal handles can absorb heat very well so it would easily spread through and to the metal handle which heats it up making it hot!
The metal handle of the pot becomes hot due to the process of conduction, where heat is transferred through direct contact of particles. As the pot is heated from the stove, energy passes from particle to particle, causing the handle to also warm up over time. This is a result of thermal conductivity in metals that allows effective heat transfer.
