Because salt is hygroscopic - can easily absorb or adsorb water.
When table salt (sodium chloride) becomes damp from water in the air, it absorbs moisture and can dissolve slightly, forming a saturated solution around the salt crystals. This process is known as deliquescence. The dampness can cause the salt to clump together and lose its free-flowing texture. Ultimately, it still remains sodium chloride, but in a more hydrated state.
A salt that loses its water of crystallization upon exposure to air and turns into an amorphous powder is called a "hygroscopic salt." These salts absorb moisture from the air, which can lead to their degradation into a non-crystalline form. Examples include certain forms of sodium sulfate and magnesium chloride.
Table Salt has an impurity in it, MgCl2. It is highly hygroscopic i.e absorbs water. In rainy seasons, due to the presence of moisture in air, MgCl2 reacts with moisture and hence Table salt gets wet.
As air becomes warmer it becomes less dense (as long as the pressure remains constant)
Yes, common salt (sodium chloride) is a homogeneous mixture because its composition is uniform throughout. When you dissolve salt in water, the salt ions are evenly distributed, resulting in a homogeneous solution.

Table The others can be subdivided and still be what they are: half of the air is still air, half the salt is still salt, half the gold is still gold, half the nitrogen is still nitrogen - but if you cut the table in half you no longer have a table.

The salt will absorb any moisture in the surrounding air. Salt is best kept in a warm area of your home.
Air is a mixture of several gaseous elements, such as oxygen and nitrogen, and compounds, such as carbon dioxide. In the sense of the four elements, water, fire, earth, and air, air is an element.
Air cannot be classified as a substance because it is a mixture of various gases like nitrogen, oxygen, and carbon dioxide. Substances, on the other hand, are pure materials composed of one type of atom or molecule.
To effectively use rock salt for dehumidifying, place a bowl of rock salt in a damp area. The salt will absorb moisture from the air, reducing humidity levels. Replace the salt regularly as it becomes saturated with water.
The examples of homogenous mixtures are table salt,table sugar,brass,air,sodium chloride solution,sugar solution,brandy and wines.that is all I got.
All matter is a substance.
they turn green due to oxidation. in iron it is red and called rust, in copper it is called patina
Table salt is sodium chloride combined with iodine sources (for nutrition), stabilizers for the iodine, and anti-caking compounds to make it pour by preventing it from absorbing water from the air.
