Question

what is the term for the transfer of heat through the movement of fluids such as air or water?
1 insulation
2 conduction
3 convection
4 radiation

Explanation:

To solve this, we recall the definitions of heat transfer methods:

• Insulation: Reduces heat transfer, not a transfer method.
• Conduction: Heat transfer through direct contact (solids, usually).
• Convection: Heat transfer via fluid (air, water) movement.
• Radiation: Heat transfer via electromagnetic waves (no medium needed).

The question describes heat transfer through fluid movement, so the correct term is Convection.

Answer:

1. Convection
