Question

Which of the following materials is useful for making molds because it has a low melting point

Answer 1

Answer:

Clay

Explanation:

Wood has higher thermal conductivity and it can be cooled easily and metal also posses high thermal conductivity and it also can be cooled easily.

The transformation of the wax can be very hard when it is present in the cooler climate conditions. It becomes hard because of the presence of lipid in it.

Clay is a soil material or natural rock which is finely grained . And the melting point of the clay is low by which it can be used for making molds.

Answer 2

The answer would be C.) clay The wax can turn really hard and can be unbreakable when present in colder materials due to the lipids present in it. Clay however can become a mold because of its low melting point.
