These are both made mostly of carbohydrates.
chunk
a lot
It is lump sugar
Ground sugar has a larger surface area compared to a lump of sugar, leading to more sugar molecules being in direct contact with the solvent. This increased surface area allows for quicker dissolution as more sugar particles can interact with the solvent simultaneously.
Powdered sugar crystal
The finer the grains of sugar, the more surface area of individual grains is exposed to the heat. A solid lump of sugar has to melt from the surface into the centre - therefore, initially, has less surface exposed to the heat.
The icing sugar has a greater surface area than the lump and so the reaction occurs more easily with the icing sugar powder. This in general applies to many salts and soluble compounds.
The process is called diffusion, where the sugar particles move from an area of high concentration (the lump of sugar) to an area of low concentration (the rest of the water) until they are evenly distributed.
The answer is that the yeast makes the bread rise making it alot more tastier than a hard lump of rock
Well, diabetics do not literally eat a 'lump of sugar', but they do eat glucose tablets, which is basically all sugar (but in an edible form). If their blood sugar level is low, they eat the glucose tablet (as you refer to as the 'lump of sugar'), and the sugar (glucose is the same thing as sugar, just a different name) from the glucose tablet increases the blood sugar levels in that person's body, but it does not take immediate affect. The glucose tablets will then increase the blood sugar levels, thereby stabilizing the body's condition. (Having low blood sugar can lead to fainting, so they take it to keep from fainting.) Diabetics who need to use insulin can become hypoglycemic and require more sugar to balance excess insulin.
