monosaccharides

Glucose is called glucose. It is a "monosaccharide" - "saccharide" meaning sugar, "mono" meaning "only one molecule of it." There are also disaccharides (two molecules stuck together), trisaccharides (three) and polysaccharides (more than three and possibly thousands depending on what it is).
Carbohydrates Monosaccharides and disaccharides are what kind of molecules? Monosaccharides are the simplest form of carbohydrates, disaccharides are carbohydrates composed of 2 monosaccharides.
One piece of sugar is a grain, which is also the same for salt. E.g., a grain of sugar or a grain of salt.
Sucrose, glucose, dextrose, maltose, xylose, they are all white. Our table sugar is usually sucrose from sugar cane or beets. I have seen some with some dextrose mixed in. Confectioners sugar often has corn starch in it. Read the labels
Sugar cubes don't actually "dissolve" in water in the sense that a salt might. Sugar breaks apart into individual non-polar sugar molecules. (relative polarity hinges on the specific species of sugar) Sugar makes a homogeneous mixture in water. Adding salt to the equation makes no real difference in the solubility of sugar in water, sugar still refuses to dissociate into ions so it remains sugar, just fragmented at the molecular level.
Single sugar molecules are also called monosaccharides.
There are many different compounds called "sugar". You'd have to be more specific. Also, sugars are polyatomic molecules.
The sugar molecules separate and disperse in the water, occupying the spaces between the water molecules. This does not change the volume of the solution, so the level of water does not rise.
simple sugars[Gk. monos, single, and sacchar, sugar], consisting of only a single sugar molecule
Carbohydrate molecules are made up of small sub-units called sugars. Carbohydrates also contain the elements hydrogen, oxygen and carbon.
Finely ground sugar is Castor sugar also called superfine sugar. Icing sugar is also a very finely ground sugar
The three carbohydrates -- sugar, starch and fiber -- are all made from molecules of sugar. However, sugar also refers to a type of carbohydrate. Sugars, or simple carbohydrates, contain just one or two molecules of sugar. Among the compounds that belong to this family are cellulose, starch, glycogen, and most sugars. There are three classes of carbohydrates: monosaccharides, disaccharides, and polysaccharides. The monosaccharides are white, crystalline solids that contain a single aldehyde or ketone functional group.
They are still called molecules. You could also call them compounds.
glucose, also known as sugar
Stirring enhances not only sugar dissolving in tea, but the same phenomenon applies every time a solid is dissolved in a solvent (the liquid phase). Let's look at what happens if a sugar crystal dissolves in tea: The sugar molecules leave the crystal and enter into the tea surrounding it. After some time you have a high concentration of sugar molecules just next to the remaining crystal. Now we have to consider another effect: The tea (or any solvent for that matter) can only accommodate a certain amount of molecules being dissolved in it (in our case the sugar). When the limit is reached there is no space (simply put) for any more sugar molecules left. Stirring removes the sugar molecules next to the remaining sugar crystal by distributing them in the rest of the tea, so that now there is new space for additional sugar molecules to exit from the crystal into the tea. Without stirring, the sugar molecules also get distributed through your whole cup of tea, by a process called diffusion, but this is much slower than simply stirring the tea.
It's also known as spun sugar.
Glucose is formed in photosynthesis when two molecules are joined together. These two molecules are ATP and CO2 (carbon dioxide).
