    How long does it take the Sun to melt a block of ice at 0oC with an area of 1.20 m2 and thickness 1.03 cm? Assume that the Sun's rays make an angle of 33.5o with the normal to the area, and that the emissivity of ice is 0.0600.

    Answer:

    During the melting the temperature of ice remains constant at 00C. The amount of heat absorbed by the block is utilized to provide the necessary ...

    Solution Summary

    Intensity of thermal radiation at an angle/ the energy absorbed by ice block/ time required is calculated.
