Holding a hot cup of coffee uses which heat transfer mechanism?

Explanation:
Holding a hot cup mainly demonstrates conduction. Heat moves through direct contact from the hot surface of the cup (and the hot coffee inside) into your cooler hand via the cup material. The efficiency of this transfer depends on the material—metal conducts heat well, so your fingers feel a stronger warmth than with ceramic. Radiative heat from the hot surface and any air convection around the cup can add a little heat, but they’re not the main path here. Evaporation is about liquid turning into vapor and isn’t how your hand gains heat in this situation. So, conduction is the primary mechanism.
