Because salt water already has NaCl(salt) dissolved into it. Water molecules can only break down so much, and so fast to combine with other molecules. When you dissolve sugar in tap water, there are not many different substances dissolved into it yet, so it's easier for the sugar cube to dissolve.
Yes
Granulated sugar would dissolve faster because there is more surface area exposed to the water.
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.
A reaction required the sugar in solid form being mobile in solution and since the sugar cube had a lot of pore and hidden surface area, the rate of dissolution would be faster and hence faster chemical reaction.
Dissolving will depend on surface area. Castor sugar has a smaller particle than regular sugar. The smaller the particle the larger the surface area. Surface area: Regular sugar < castor sugar < icing sugar. Castor sugar should dissolve faster than the same mass of regular sugar but slower than the same mass of icing sugar.
Crushing the sugar cube allows more surface area with the water that hydrates (dissolves) the sugar molecules. Therefore, it will dissolve faster. Stirring helps.
The surface tension of water is due to the hydrogen bonds contained in it.When sugar is added to it,the dissolution process occurs which leads to the breaking of the hydrogen bonds in water by the hydration energy generated by the interaction of sugar and water.Therefore sugar reduces the surface tension in water
grown sugar dissolves faster than a cube because grow sugar has more surface area
Diet Coke erupts when you add sugar to it because the sugar lowers the surface tension in the soda. The bubbles will then be able to break the surface and cause the eruption.
Granulated sugar would dissolve faster because there is more surface area exposed to the water.
It has more surface area.
Granulated sugar has more surface area exposed to the coffee, therefore it will dissolve faster.
It has a larger contact surface with the liquid that dissolves it.For the cube it is just the outer surface that is in contact with water. For the spoonful, water surrounds every single grain at the same time.
sugar because it has dendancy in it
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.
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.
Powered sugar dissolves faster because it has more surface area.
i think its because caster sugar has smaller particles!!:)
