Questions & Step-by-Step Solutions
Which of the following is an example of forced convection?
Step 1: Understand what convection is. Convection is the process of heat transfer through fluids (liquids or gases) where warmer areas rise and cooler areas sink.
Step 2: Know the difference between natural and forced convection. Natural convection happens without any external force, while forced convection involves an external force, like a fan or a pump, to move the fluid.
Step 3: Consider the example of boiling water. When water boils, the heat from the stove warms the water at the bottom of the pot. This warm water rises, and cooler water moves down to take its place, creating a circulation.
Step 4: Identify if there is an external force. In a pot of boiling water, the heat from the stove is the external force that causes the water to circulate, which is an example of forced convection.
