Answer :
Answer: Boiling water is a combination of conduction and convection.
Explanation:
Conduction is the transfer of heat through a solid or liquid material by the movement of atoms or molecules. In the case of boiling water, heat is conducted from the heat source (such as a stove or hot plate) to the bottom of the pot or container, causing the water at the bottom to heat up and eventually boil.
Convection is the transfer of heat by the movement of a fluid or gas. When the water begins to boil, it forms bubbles of steam, which rise to the surface and carry heat away from the boiling water. This is known as natural convection. In some cases, the water is heated by a heating element that is in contact with the bottom of the pot or container, this is known as forced convection.
Radiation is the transfer of heat through electromagnetic waves, such as infrared radiation. Boiling water doesn't rely on radiation as the main heat transfer mechanism, as the heat is transferred mainly through conduction and convection. However, some heat may also be transferred by radiation, especially if the pot or container is made of a good thermal conductive material and the surface of the water is exposed to the air.
Boiling water involves heat transfer primarily through convection.
When considering the heat transfer process involved in boiling water, we are looking primarily at convection. Convection is the heat transfer mechanism that occurs when heat is carried away by the movement of mass. Inside the pot, the hotter water at the bottom expands, becomes less dense, and rises to the top, while the cooler water descends to take its place, creating a circulation pattern.
This process is different from conduction and radiation. Conduction refers to the transfer of heat through direct contact between materials, and radiation refers to the transfer of heat through electromagnetic waves.
