When a plate of hot food is left on table it cooled by?

A plate of hot food cools down on the table due to a combination of these processes:

* Conduction: The heat from the food transfers directly to the plate, the table, and the surrounding air molecules that are in contact with it.

* Convection: The warmer air around the food rises, carrying heat away, and is replaced by cooler air. This creates a convection current that helps cool the food.

* Radiation: The food emits infrared radiation, which carries heat away from the food.

These three processes work together to transfer heat energy from the hot food to the cooler surroundings, causing the food to cool down.
