Crystalline solids do not have a sharp melting point.
true
false

False

Explanation:

A crystalline solid has a well ordered structure. The particles that make up the solid are arranged in a regular repeating pattern. When the solid is heated, this structure gives way, in order words, the solid melts.

Pure solids crystals are known to have sharp melting points. This is a property of crystalline solids.

if the temperature drops and becomes cool

then the atmosphere can be freezing as the water vapor in the air is at maximum (100%) and can be severely cold

also can be snowing lightly as the moisture in the air will start to solidify

and btw this is not chemistry but
