b. saturation

c. boiling point

d. volume

2. which of the following reasons explains why electrical cords are plastic coatings with metal wires on the inside?

a. both plastic and metal have high electrical conductivity.

b. both plastic and metal have low electrical conductivity.

c. plastic has high electrical conductivity, and metal has low electrical conductivity.

d. plastic has low electrical conductivity, and metal has high electrical conductivity.

1. Answer;

Solubility

Explanation;Solubility is the property of a substances, which is the capability of a given substance, that is called a solute to dissolve in a solvent such as water. in other words it is the degree at which a solute dissolves in a solvent to form a solution.Solubility describes the ability of a substance to dissolve in a solvent at a given temperature. it is measured as the maximum amount of solute that can dissolve in a solvent such as water at a particular temperature. 2. Answer;

D. Plastic has low electrical conductivity, and metal has high electrical conductivity.

Explanation;In terms of electrical conductivity materials may either be good conductors or bad conductors also insulators.Good electrical conductors are those materials that allow conduction of electricity with ease, like metals such as copper. Such materials have very high conductivity of electricity.Bad conductors or non conductors are those that have low conductivity of electricity, thus they are used as insulators, they include plastics, wood, etc.In this case metal has high electrical conductivity while plastic coatings have low electrical conductivity and thus used as insulator.
