Sodium chloride is hygroscopic, absorb water.
Solid sodium chloride is not conductive; the water solution of NaCl (or wet NaCl) being an electrolyte is conductive.
Sodium chloride is hygroscopic, meaning it can absorb moisture from the air, but it is not deliquescent, which refers to substances that absorb so much moisture they dissolve in it. In the rainy season, the high humidity in the air allows the sodium chloride to absorb enough moisture to become wet, even though it doesn't dissolve completely.
Yes, anhydrous calcium chloride is hygroscopic, meaning it absorbs water from its surroundings. When it becomes wet, it can release heat rapidly and cause burns or irritation on contact with skin. It can also release irritating or harmful fumes if it comes in contact with water.
The released heat of solubility for sodium chloride lower the freezing temperature of ice.
it becomes wet not red
The answer to the analogy "water is to wet as dust is to what" would be dry. Water becomes wet when it comes in contact with it, similarly, dust becomes dry when it is not wet or has not come in contact with water.
It becomes wet.
no
Warm and wet
Yes, many deserts have a wet winter season.
