State True or False. Give reasons for your answer.

Alloys have high melting point.

$\underline {\underline{{\purple{ \sf ANSWER:-}}}}$

➳ False. Alloys do not have a high melting point.

➳ Alloys have a low melting point.

$\underline {\underline{{\purple{ \sf REASON\:WHY\:ALLOYS\:HAVE\:LOW\:MELTING\:POINT:-}}}}$

➳ The different sizes of atoms in an alloy make their arrangement less regular than a pure metal.

➳ This makes the bonds between the atoms weaker, and lowers the melting point.

➳ Alloys that melt easily, have important uses.

$\underline {\underline{{\purple{ \sf SOME\:ALLOYS\:HAVING\:LOW\:MELTING\:POINT:-}}}}$

➳ Some alloys that have low melting point are gallium, tin, zinc, antimony, mercury and lead.
