ICSE Class 7 Answered

The top of a roof made of asbestos is painted white.Why?
Asked by rajp71661 | 29 Dec, 2018, 08:49: AM
answered-by-expert Expert Answer
maximum reflection or scattering out  of incident radiation is possible only with white colured surface.
Hence most of the incident radiation due to sunlight will be reflected back or scattered out.
Asbestos will absorb less amount of radiation and is heated less if the surface is painted as white.
Hence temperature below asbestos will be moderate
