To remove moisture from the air, you can use a dehumidifier, which draws in humid air and condenses the moisture into water. Alternatively, air conditioning units also help reduce humidity by cooling the air and removing excess moisture. For smaller spaces, desiccants like silica gel or calcium chloride can effectively absorb moisture.
Water is a substance composed of two hydrogen atoms and one oxygen atom, existing in liquid, solid, or gaseous form. Moisture refers to the presence of water molecules in the air or in a substance, making it slightly wet or damp. Essentially, water is the liquid form of the substance, while moisture refers to water in a different context or state.
A substance with the ability to remove water from the air and create a solution is called a desiccant. Desiccants are commonly used in industrial processes, in products like moisture-absorbing packets found in food packaging, or in moisture control applications in buildings.
When exposed to air, calcium chloride can absorb moisture and become hydrated, forming a white, powdery substance. It is hygroscopic, meaning it has a strong affinity for water molecules in the air. This property allows calcium chloride to be used as a desiccant to remove excess moisture from the air.

Glycerol, also known as glycerin is a humectant that draws moisture from the air to the skin in humidity above 65%. Below that humidity, it draws moisture from the deeper layers of the skin to the surface, causing dehydration.

Weighing an anhydrous substance with a cover on helps prevent moisture from the air from being absorbed by the substance, which could affect the accuracy of the measurement. By keeping the cover on during weighing, the substance is protected from exposure to moisture or other contaminants.
