The photo shows metal pipes that are meant to carry water. The pipes are surrounded by a layer of foam insulation covered by an outer layer of
reflective material,
When it's freezing outside, how does this insulation prevent the pipes from
bursting?
A. The foam is a good thermal conductor that speeds the transfer of
energy to the water in the pipe.
B. The foam has tiny air pockets that slow the transfer of thermal
energy away from the water in the pipe.
C. The outer reflective material prevents the absorption of thermal
energy by the water in the pipe.
D. The outer reflective material prevents coldness from entering the
pipe through radiation.
