Answer :
Final answer:
Water boiling on a stove is an example of both conduction and convection. Conduction transfers heat from the stove to the pot, while convection circulates heat throughout the water. These processes work together to efficiently heat the water.
Explanation:
Understanding Heat Transfer in Water Boiling
Water boiling on a stove is a classic example of convection and conduction. To clarify these concepts:
- Conduction: This is the transfer of heat through a material when there is direct contact. For instance, the heat moves from the burner of the stove to the bottom of the pot through the metal of the pot.
- Convection: This occurs in fluids (liquids or gases) when there is a circulation pattern due to temperature differences. In a boiling pot of water, the hotter water expands, becomes less dense, rises to the surface, while colder water sinks to the bottom, creating a continuous circulation. This process effectively distributes heat throughout the liquid.
In summary, boiling water demonstrates how heat is transferred both through conduction from the stove to the pot and via convection as the water circulates.
