Granulated sugar has more surface area exposed to the coffee, therefore it will dissolve faster.
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.
Neither since the melting point of sugar is 365 F and the melting point of salt is 1474 F
Ice cubes cool lemonade faster than ice water because they have a larger surface area for heat transfer. When ice cubes are added to lemonade, they melt and absorb heat quickly, cooling the drink faster.
Sugar has very little effect on melting point - it is too high molecular weight. That might answer your question, which does not make sense as written. Thus, it melts faster with sugar, because other ice cubes slow melting.
Ice cubes will melt faster in water than in cola. This is because water has a higher thermal conductivity than cola, allowing for faster heat transfer to the ice cubes, causing them to melt more quickly.
To dissolve sugar cubes, simply place them in a liquid (such as water, coffee, or tea) and stir until the cubes break down and the sugar dissolves. The smaller the sugar cubes, the faster they will dissolve. Heat can also help speed up the process.
Sugar cubes would dissolve faster when crushed rather than left whole, regardless of whether the water used is hot or cold. Crushing the sugar cubes increases the surface area of the sugar particles exposed to the water, allowing for quicker dissolution.
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.

Hot water
sugar cubes
To quickly cool down your coffee, you can add ice cubes or place the coffee in the refrigerator for a few minutes. Stirring the coffee can also help it cool faster.
sugar cubes dissolve faster than limestone
Sweet, granulated, white, cuboid.
Sugar Crystals Dissolves Faster In Distilled Water Then In Tap Water Because Distilled Water Is Water That Has Essentially All Minerals Removed. Tap Water Has Nasty Invisible Substances In It Such As Pesticides And Weed Killer Makin The Sugar Dont Dissolve
Ice melts because of heat, coffee dissovles because of the hot water
My experience is the finer the grain, the quicker it dessolves. Make some scientific sense too as, to dissolve, it must be broken down. So if the solute (sugar) is already partially broken down mechanically, there's less "work" for the solvent (the liquid you are dissolving it into) in creating the solution. So, powered sugar.
