Sulfur
When you burn sulfur, you create sulfur dioxide, which is approximately twice the molar weight of regular sulfur. Wetting sulfur does not decrease it's weight.
None. The mass of an object won't change if you change the state of matter. When you burn it, the mass can change, since the atoms of the original object combine with oxygen, usually.
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.
When it gets wet.

SULFUR
The wet towel gets dry by the process of evaporation. Wet clothes hung outside on aclothesline dry by evaporation.
When a wet towel is left in the sun it eventually becomes dry, it is dried through the process of evaporation.
Sulfur
the wet weight is 132 kilo's ,(then again it may be dry weight)
Sulfur is closely match this puzzle. The density of 2 kg sulfur is double than 1 kg water. So if you weigh the sulfur in immersed state, the weight of sulfur will be 1 kg. Sulfur will displace about 1 kg water and will lose the same weight. After taking out of water, 2 kg sulfur will be 2 kg only. When you burn the sulfur, it will combine with 2 kg oxygen and you will get 4 kg of sulfur bi oxide. So it is fairly close to the answer. 3 kg literally means more than 2 kg. May be you know the better answer.
