Question
In years of heavy snow pack in the mountains it is sometimes desirable to induce early melting of the snow, rather than wait until it all melts suddenly and causes floods. It has been suggested that a way to accomplish this might be to have planes fly over and sprinkle them with black soot. Would it work? A. No , it would not work because it is infrared radiation and not visible radiation which melts the snow B.Yes, it would work because the soot would decrease the specific heat capacity of the snow. C.Yes, it would probably work because the black surface would be a better absorber of sunlight than the white snow D.No, it would not work because sunlight has little effect on how fast the snow melts E.Yes, it would work because the soot would raise the melting point of the snowExplanation / Answer
soot basically prevents the snow from reflecting back the sunlight that falls on its surface. so you may say that black surface is a good absorber of sunlight. so it may be C
