How do convection and conduction differ in terms of heat transfer?

1. Convection occurs strictly in winter

2. Convection involves heat transfer through solid objects

3. Conduction is heat movement through windows

4. Convection is hot air rising, conduction is heat transfer through materials

5. Convection is related to sunlight, conduction is related to gas heat

6. Conduction involves heated liquids only

The correct answer is: Convection is hot air rising, conduction is heat transfer through materials

Convection and conduction differ in terms of heat transfer because convection is related to hot air rising, while conduction is related to heat transfer through materials. In convection, heat is transferred through the movement of a fluid (such as air or water) as it becomes less dense and rises. Conversely, conduction is the process of heat being transferred through a solid material by direct contact. This distinction is important in understanding how heat is transferred in different scenarios and environments. Options A, B, C, E, and F are incorrect because they do not accurately describe the differences between convection and conduction in terms of heat transfer.
