Question

Is boiling water conduction or convection?

Answer 1

Hint: Heat transfer is described in thermodynamic systems as the flow of heat beyond the system's boundary due to a temperature differential between the system and its surroundings. Surprisingly, the temperature differential is claimed to constitute a "potential" that causes heat to move from one spot to another. Heat is sometimes referred to as flux.

Complete answer:
The process through which heat travels from things with higher temperatures to those with lower temperatures is known as conduction. Thermal energy is transferred from a higher kinetic energy area to a lower kinetic energy area. When high-speed particles collide with slow-moving particles, the kinetic energy of the slow-moving particles increases. This is a common type of heat transmission that occurs through physical contact. Conduction is sometimes referred to as thermal or heat conduction.
The flow of fluid molecules from higher temperature regions to lower temperature regions is known as convection. When water boils, the molecules that are denser sink to the bottom and the ones that are less dense rise, resulting in a circular motion of the molecules, which heats the water.
Conduction and convection are both involved in boiling water. Heat is transmitted from the heat source to the water at the bottom of the container by conduction, and heat is moved within the water via convection.

Note:
When molecules at the bottom of a cooking pot rise and warm, while colder and heavier molecules sink, this is known as natural convection. This generates a circulating current that distributes heat evenly across the item being cooked.
When you put a pot of water on the stove to boil, for example, conduction heat warms the vessel, which then heats the water molecules within. Convection causes these molecules to migrate out from the pot's interior as they heat up and are replaced by cooler ones. Within the water, this constant stream causes convection heat transfer.
