A) Conduction
B) Convection
C) Radiation
D) None
Correct Answer: B
Solution :
Conduction is the process of transmission of heat in a body from the hotter part to the colder part without any bodily movement of constituent atoms or molecules of the body. In convection, the heated lighter particles move upward and colder heavier particles move downward to their place. This depends on weight and hence, on gravity. Radiation is the process of transmission of heat from one body to another body through electronegative waves even through vaccum, irrespective of their temperatures. Hence, choice (b) is correct.
