A) Conduction
B) Convection
C) Radiation
D) In all these heat is transferred with the same speed
Correct Answer: C
Solution :
Key Idea: Process is fastest where medium is not required. There are three modes of heat transfer conduction, convection and radiation. Out of which the process of conduction and convection require a medium for propagation while the process of radiation is done in vacuum also with speed of light, hence speed of transfer of heat is maximum in it.You need to login to perform this action.
