Assertion : Greater is the coefficient of thermal conductivity of a material, smaller is the thermal resistance of a rod of that material. Reason : Thermal resistance is the ratio of temperature difference between the ends of the conductor and rate of flow of heat.

If the specific heat of lead is 0.03 cal/gm, then the thermal capacity of 500 gm of lead will be

The ends of the two rods of different materials with their lengths, diameters of cross-section and thermal conductivities all in the ratio 1 : 2 are maintained at the same temperature difference. The rate of flow of heat in the shorter rod is 1cals^(-1) . What is the rate of flow of heat in the larger rod:

A cylinder of radius R is surrounded by a cylindrical shell of inner radius R and oputer radius 2R. The thermal conductivity of the material of the inner cylinder si k_(1) and that of the outer cylinder is K_(2) ,Assumming no loss of heat , the effective thermal conductivity of the system for heat flowing along the length of the cylionder is :

STATEMENT-1: The thermal conductivity of a rectangular slab of a material can be defined only under steady-state conditions, i.e, when the temperatures of the end faces do not changes with time. STATEMENT-2: The rate of conduction of heat through a reactangular slab is proportional to the difference in temperature between its end faces.

A cylinder A of a material of thermal conductivity K_(1) is surrounded by a cylindrical shell of inner radius equal to the cylinder. The shell is made of a material of thermal conductivity K_(2) . The two ends of the combined system are maintained at two different temperature. if the effective thermal conductivity of the system is (4K_(1) + 5K_(2))/(9) , find the rate of outer radius of the shell to the radius of the cylinder.

(a) Calculate the rate at which body heat is conducted through the clothing of a skier in a steady-state process, given the following data : the body surface area is 1.8m^(2) , and the clothing is 1.0 cm thick , the skin surface temperature is 33^(@)C and the outer surface of the clothing is at 1.0^(@)C , the thermal conductivity of the clothing is 0.040 W//m . K. (b) If , after a fall, the skier's clothes became soaked with water of thermal conductivity 0.60 W//m.K , by how much is the rate of conduction multiplied ?
