Answer:
The thermal transfers via "Conduction and Radiation"
Step-by-step explanation:
Because, Convection is the transfer of thermal energy by particles moving through a fluid. Thermal energy is always transferred from an area with a higher temperature to an area with a lower temperature.
Moving particles transfers the thermal energy through a fluid by forming convection currents.
It transfers ( thermal ) heat energy to a food's surface via convection and radiation. So that, the heat energy on the food's surface, then it spreads via "conduction" towards the food's center.
