Statement 1: A mixture of pure metals is called an alloy. The melting point of an alloy will be lower than either of the component metals
Statement 2: The new bonds are weaker
A.Statement 1 and statement 2 are correct statement and statement 2 is the correct explanation of statement 2.
B.Both the statement 1 and statement 2 are correct, but statement 2 is not the correct explanation of statement 1.
C.Statement 1 is correct, but statement 2 is not correct.
D.Statement 1 is not correct, but statement 2 is correct
Solution
We know that alloy is a combination of metals or metal combined with one or more other elements. The melting point of a substance is the temperature at which the solid form of a substance changes to liquid. At the melting point, both the phases are in equilibrium.
Complete step by step answer:
We know that alloy is a combination of metals or metals combined with another element.
The melting point of an alloy will be lower than that of component metals because metals in their native state have regular state and have a regular arrangement so they form a strong bond and have a lower melting point.
Whereas on another hand on forming alloys the regular structure breaks due to the mixing of elements of different sizes and properties so the alloy becomes less regular and the bond becomes weak and it lowers the melting point. So by this conclusion statement, one is correct and statement two is also correct.
As the new bond formed is weak so the statement second is also correct.
Therefore, statement one and statement two are correct and statement two is the correct explanation of statement one.
Hence the correct option is A.
Note:
There is a variation between the melting point of alloys and that of constituent metals present in the alloy by which they are formed so that should be kept in mind .It is due to the arrangement of the atoms in the metal and after the formation of alloy which affect the melting point.
