Why does salt clump in humid weather and why does condensation sometimes form on the top of the salt shaker?

Fur usually coats the body of the animal and is closely packed.  It is also finer in texture.  It typically has two layers and its function is is trap pockets of air to keep the animal warm.

Have you ever noticed how you have less candle after burning than before? This is because the wax oxidizes (burns) in the flame to yield water and carbon dioxide, which dissipate in the air around the candle, in a reaction which also yields light and heat. Candle wax (paraffin) is composed of chains of connected carbon atoms surrounded by hydrogen atoms. These hydrocarbon molecules can burn completely. First the heat of the flame vaporizes the wax molecules and then they react with the oxygen in the air. As long as the wax doesn't melt away from the flame, the flame will consume it completely and leave no ash or wax residue.

Salt is hydroscopic. Because of the net positive charge of its chemical components, it can attract atmospheric water, which has a net negative charge. In solution in water, sodium chloride (salt) dissociates into its chemical elements and the sodium ions are attracted to the negative end of water molecules and chloride ions are attracted to the positive end (hydrogen).
