Question

Definition and derivation of co-efficient of thermal conductivity

Answer 1

coefficient of thermal conductivity a number indicating the quantity of heat passing in a unit of time through a unit thickness of a substance when the difference in temperature is 1°C. coefficient of thermal expansion the change in volume per unit volume of a substance produced by a 1°C temperature increase.
