The process of heat transfer from one particle of the fluid to another by the actual movement of the fluid particles due to difference of density caused by temperature of the particle is known as
A. Conduction
B. Free convection
C. Forced convection
D. Radiation
Answer: Option B
Solution (By Examveda Team)
Free convection heat transfer is the transfer of heat due to movement of liquid and air molecules without external source such as a pump or fan.It occurs due to forces generated by density differences caused by temperature difference.
