Answer 1

a)i)Dull black surfaces are good absorbers and radiators of heat.

ii)Shiny/silvery surfaces are poor absorbers and radiators of heat.

iii) White is a good reflector of heat.

b)Those materials or metals that have larger surface area are expected to radiate heat faster as compared to those materials that have low surface area. The good radiators are also expected to have high thermal conductivity. The materials or metals like copper, aluminium and brass radiate the heat better.
