How does a shiny , silver and smoothsurface reduce the heat loss of a hot object to its cooler surroundings

Shiny surface are poor radiators of heat

A shiny , silver and smooth surface reduce the heat loss of a hot object to its cooler surroundings because good radiators and good absorbed of heat have dull, black and rough surfaces while on the other hand poor radiators have smooth and shiny surfaces therefore they reduce the heat loss of a hot object.

r = ρ x length / area  

ρ = r x area / length  

ρ is in ohm-meters  

in basic units, it is m³kg/s³a²  

i think this is it.

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
