The factors for dissolving sugar are:
Granulated sugar has more surface area exposed to the coffee, therefore it will dissolve faster.
Sugar will dissolve faster in hot water than it will in cold water.
Heat the water to boiling point, then put the rock sugar in
Temperature: more sugar will dissolve in water at a higher temperature. The amount of water is also a factor, since more water will be able to dissolve more sugar. If you are wondering about the rate, and not simply the amount, of sugar dissolving, then the surface area of the particles is also important. The greater the surface area, the more rapidly it will dissolve (smaller grains of sugar would dissolve more rapidly than a sugar cube, for instance).
grown sugar dissolves faster than a cube because grow sugar has more surface area
Sugar should dissolve faster in a liquid.
Warm Water (The high temp. may cause the sugar particles to met/dissolve)
The sugar cube in the hot water will dissolve faster because there are more and higher energy collisions between the water molecules and the sugar molecules which will cause the sugar to dissolve faster.
The difference is minimal; the white sugar dissolve a bit faster beacause doesn't contain impurities.
Granulated sugar has more surface area exposed to the coffee, therefore it will dissolve faster.
Yes
will the dum dum dissolve faster in salt water or sugar or just water
Sugar is less dense than salt, leading to it dissolving faster.
Sugar dissolves faster than salt in water. Salt has stronger bonds than sugar. That what makes sugar dissolve faster (because it has weaker bonds and structure than salt)
Heat it
No
Sugar is more soluble.
