Unit of thermal conductivity in M.K.S. units is
A
K cal/kg m<sup>2</sup> °C
B
K cal m/hr m<sup>2</sup> °C
C
K cal/hr m<sup>2</sup> °C
D
K calm/hr °C
Correct Answer: K cal m/hr m<sup>2</sup> °C
Thermal Conductivity is the quantity of heat that passes in unit time through unit area of a substance whose thickness is unity, when its opposite faces differ in temperature by one degree.Unit of thermal conductivity in M.K.S. units is K cal m/hr m2 °C.
