Answer / sekar

absorptivity = 1

Answer / jayesh

ideal black bodu absorbs whole amt of radiation inserted on it
thus absorbance = 1

as the body absorbs all thing thus reflects none
so reflectivity = 0

now good absorber is always good emitter for the case of black body
emissivity = 1

following this sequence answer is (A)

Answer / manikandan

Emissivity = 0

Question 80 - Liquid octane has a density of 703 kilograms per cubic metre and molar mass of 114.23 grams per mole. Its specific heat capacity is 255.68 J / (mol K). (a) Find the energy in J needed to increase the temperature of 1 cubic metre of octane for 1 Kelvin. (b) At 20 degree Celsius, the solubility of liquid octane in water is 0.007 mg / L as stated in a handbook. For a mixture of 1 L of liquid octane and 1 L of water, prove by calculations that liquid octane is almost insoluble in water.
