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.

B. The foam has tiny air pockets that slow the transfer of thermal

energy away from the water in the pipe

Explanation:

Air is a poor conductor thermal energy and can be used as good insulator. Insulators are poor conductors of heat.

When it is freezing outside, the temperature gradient will tend to adjust to the ambient one. The water in the pipe being at a higher temperature will tend to lose heat energy to the surrounding.

The layer of foam will prevent this form of heat exchange from happening because of the air pocket that is present around.

one characteristic that is shared by all is a soft body. many

of these invertebrate animals also have an outer shell to protect their

body. oysters, clams, snails, and mussels are all mollusks. so are octopuses, squids, and slugs. mollusks live on land and in freshwater.
