Question

The letters CHEMISTRY were spray painted in blue paint on the snow. After a while the sun comes out and the snow under the blue paint melts while the snow around the letters do not. Why did the snow under (rather than around) the blue paint melt?

Answer 1

The snow AROUND the pair, being white, reflected more of the sunlight (the heat of it anyway)--said another way the blue paint absorbed more of the heat from the sun than the surrounding area. Voila, more heat means more melted snow.
