sugar cubes
Granulated sugar has more surface area exposed to the coffee, therefore it will dissolve faster.
A sugar cube will - one, sugar cubes are designed specifically to dissolve quickly into solvents such as tea, coffee, liquids to make solutions. Granulated sugar, on the other hand, is often a solute for solid solvents such as flour etc. However, the granulated sugar can be dissolved more quickly if stirred, which makes the solute particles attract to the solvent particles more efficiently.
Let's imagine the following objects first: Sugar cubes are solid blocks, each with a comparatively larger volume. Granulated sugar is fine and particulate, and each grain has a very small volume. It is only logical that when comparing one block of sugar to one grain of sugar, that the grain dissolves faster because it has a smaller volume (less to dissolve), and the surface area to volume ratio is much higher.
no they are same
No, caster sugar is fine-ground granulated sugar. Confectioner's sugar is a mix of ultra-fine sugar and a starch; it is sometimes called icing sugar.
Caster sugar has finer granules than regular (or "granulated") sugar. For cupcakes, you should be able to use regular sugar instead of castor without any detriment to the final product.
Usually it is plain granulated sugar that you would use for anything else. Some people prefer sugar cubes, which is suagr pressed into a small cube shape.
I never heard of crushed water. Crushed ice (which sugar cubes don't dissolve in at all), but not crushed water. Let's see here: sugar dissolves faster in hot water than cold. And crushed sugar cubes, because the sugar has more surface area, dissolve faster than cold ones.
The main distinguishing feature of confectioners' sugar is that its a very fine powder (while regular sugar is often in powder form, it is more granular, hence the name granulated). This helps the confectioners' sugar dissolve faster, which may aid in some applications.
Granulated sugar would dissolve faster because there is more surface area exposed to the water.
Fructose and granulated sugar at 99.99% and candies which are derivatives of sugar
Yes it does the powdered sugar does grow faster and the granulated sugar starts to mold
