Question

Which of the following is an example of heat transfer by convection? Question 2 options: The coils of a toaster become red. A hot wood stove heats an entire room. A teaspoon in a glass of hot tea becomes warm. The handle of a pot that is being heated becomes warm.

Answer 1

The correct option is B. A hot wood stove heats an entire room.

Step-by-step explanation:

Convection can be described as a method of heat transfer in which heat is transferred by a medium like a gas or a fluid.

The warmer air has less density as compared to cooler air. Hence, convection currents are generated which transfer heat.

In the option B, heat is being transferred by the particles of the air. The air near the stove is warmer as compared to the air in other parts of the room. Hence, a convection current is generated which transfers the heat.
