D)Radiation

Question

Quizplus · Accepted Answer

The Biot number is important in transient heat conduction because it is a dimensionless number that relates the internal thermal resistance within an object to the external convective heat transfer resistance. It helps in determining whether the temperature gradient within the object can be ignored or not.
