A sugar cube would dissolve faster than a single sugar crystal of the same mass because it has a greater surface area (sugar cubes aren't solid; they're lots of little sugar crystals stuck together). The difference in speed between a sugar cube and normal (small) sugar crystals ought to be negligible with the crystals having perhaps a slight edge.

∙ 13y agoWhen combined with liquid, the separate grains of sugar have more surface area in contact with the liquid which allows them to dissolve more quickly. Sugar cubes have grains packed tightly together so that not all surfaces of all the grains are initially in full contact with the liquid. Until the cube loses its integrity from soaking and becoming wet and the grains begin to come apart from each other, they will not dissolve as quickly.
A:Dissolving only takes place when the liquid can interact with the solid. A spoonful of sugar is loose, therefore more of the sugar touches the liquid. In a sugar cube most of the sugar is on the inside of the cube and cannot interact with the liquid until the outside dissolves.
Think of it like waiting in a checkout line at a store. If only one lane is open it will take longer than if lots of lanes are open, because you have to wait for the people in front of you to checkout. It is very much the same idea with dissolving.

Two things which affect the way sugar dissolves in water are:
Particle size.
Smaller particles will dissolve more quickly than larger particles as there is a greater surface area for the solvent (in this example, water) to react with. Think about a sugar cube. A large cube of sugar only has 6 large sides to react with the solvent, initially anyway.
Temperature.
Warm/hot water (e.g. in tea or coffee) will dissolve sugar better than cold water as the molecules in the water are more excited and have more energy.

∙ 12y agoSugar granules are spread out, increasing surface area between the granules and the water. With sugar cubes, there is less surface area because the sugar is packed into a cube. One factor in rate of reaction is surface area: the larger the surface area, the faster the reaction.

NaCl = 35.9g/100mL @ 25 deg C
Sucrose = 200g/100mL @ 25 deg C

A sugar cube is tightly compacted granulated sugar, meaning it has less surface area exposed to the solvent

Why granulated sugar will dissolve faster in a cup of coffee than sugar cubes?
Granulated sugar has more surface area exposed to the coffee, therefore it will dissolve faster.
Why do sugar cubes dissolve more slowly than granulated sugar?
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.
Which ice cubes melts faster with sugar or ice cubes?
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.
What is a good sentence for dissolve?
Sugar will dissolve faster in hot water than it will in cold water.
How do you dissolve rock sugar in water?
Heat the water to boiling point, then put the rock sugar in
Why granulated sugar will dissolve faster in a cup of coffee than sugar cubes?
Granulated sugar has more surface area exposed to the coffee, therefore it will dissolve faster.
Which will dissolve faster in powdered sugar crystal sugar or lump sugar in a glass of tap water?
Powdered sugar crystal
Do sugar cubes dissolve faster crushed or whole in hot or cold?
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.
Do sugar cubes dissolve faster in hot water or cold water?
Hot water
How is the effect of water of a sugar cube similar to groundwater eroding limestone?
sugar cubes dissolve faster than limestone
Who to dissolve sugar cubes?
water!
Why does borax crystal grow faster then sugar?
Because when you mix it the sugar starts to dissolve quicker and borax just sits there
Do sugar cubes dissolve in water?
Yes
What makes sugar cubes dissolve?
Liquid

Which will dissolve faster in liquids salt or sugar?
Sugar should dissolve faster in a liquid.
Why is it logical for sugar cubes to dissovle under cooler temperatures?
It's not. Sugar molecules dissolve faster in warmer temperatures. When molecules are heated, they become agitated, causing dissolution to occur.
