Q1:

How many phases are present at eutectic point ?

A 1

B 2

C 3

D unpredictable

ANS:C - 3

At the eutectic point, there are two phases present. The eutectic point is the lowest temperature at which a mixture of substances such as an alloy or a solution of two liquids has a particular composition and will solidify into two or more different solid phases simultaneously. So, the correct answer is: 2 phases
