Question

Inside human body, which of the following is responsible for heat transfer,
A. Conduction
B. forced convection
C. free convection
D. none of the above

Answer 1

The given problem can be resolved using the concept and the modes of heat transfer. The heat transfer can take place in three different modes, namely conduction, convection, and radiation. In the human body, the heat interaction can occur both through the solid remains and the liquid materials; these bring about the mode of convection to play a major role in the heat transfer by a human body.

Complete step by step answer:
In the human being, the heat transfer is generally taking place utilizing the convection. This is due to the reason that the human body consists of both the solid as well as the liquified organs and matter. And the mode of heat transfer that occurs through the solid-liquid interaction is known as the convection. Moreover, this heat transfer process from and to the human body is accomplished by some external force that occurs during the metabolic activities. The convection that requires an external force to appear is known as the forced convection. Thus the human body requires a force convection process to achieve the interaction of the heat energy from the external environment.

So, the correct answer is “Option B”.

Note:
Try to understand the concept behind the heat transfer by various modes, along with their significant applications. Moreover, the heat transfer utilizing convection in a human is one such example that is to be analysed. The convection is of two types, namely the free convection and the forced convection.
