As the impurity concentration in solid solution is increased, the tensile and yield strengths ____________________.

increase

decrease

Answer 1

Answer:

As the impurity concentration in solid solution is increased, the tensile and yield strengths increases.

Explanation:

The addition of impurities in solid solutions shows an improved tensile and yield strength due to the grain refinement and obstacles to the motion of dislocation.

Example, the addition of carbon as impurity into iron, which forms steel shows a significant increase in the tensile and yield strengths of iron.

Blacksmiths also use work hardening to introduce dislocation into solid solutions in order to increase their  tensile and yield strengths.

Therefore, as the impurity concentration in solid solution is increased, the tensile and yield strengths increases.

Answer 2

A solid solution is a mixture of crystalline solids and is soluble over the partial or evenly complete range.

• A solute may be replaced by a solvent particle. It may be used for heating the is related to the melting point.

• The tensile and strength of the solution form a solid increase as the concentration of the impurities increase.

Hence the option Increases is correct.
