Question

Identify the statement in which the mode of heat transfer is convection ?

• A. The heat of the sun warming our planet
• B. The heat from an electric stove warming a frying pan
• C. A microwave oven cooking a meal
• D. An overhead fan cooling a room
• E. Ice cubes cooling a drink

Answer 1

Answer: (E)

When an ice cube melts in a drink, the molecules of the drink at a higher temperature come to the ice cube and cool down. Whereas the melted particles of ice go to fulfill the empty space from where molecules of the drink have come. As the particles are moving in this heat transfer, so it is convection.
