Question

Vhen two or more substances are mixed and liquefy due to formation of new
components which has lower melting point than room temperature are
called....
A) Elflorescent powder
B) Deliquescent powder
C) Higroscopic powder
D
Eutectic mixtures​

Answer 1

Answer:

D)Eutectic Mixtures

Explanation:

Eutectic mixtures:- When two or more substances are mixed together they liquefy due to the formation of a new compound which has a lower melting point than room temperature . Such substances are called eutectic substances.

Answer 2

Option (D) Eutectic mixtures​

When two or more substances are mixed and liquefy due to the formation of new components which has a lower melting point than room temperature are called Eutectic mixtures​.

Explanation:

• The eutectic mixture is the mixture that has a specific composition with two solid components which produces a change of phase to liquid at a temperature.
• The temperature is given a name as Eutectic point and it corresponds to the minimum melting point with different possible compositions.
• It is a mixture of two or more phases at a particular composition of materials which have a lowest melting point and at that temperature, the phase will crystallize.
• An example of an eutectic mixture - Sodium chloride and water forms a eutectic mixture whose eutectic point is −21.2 °C and 23.3% salt by mass.
