Because the Sugar molecules are dissociated and fit in the space of H2O molecule arrangements. Hence no increase in the volume.
The observation that there is no increase in volume when sugar is dissolved in water illustrates the characteristic of matter known as "volume conservation." This phenomenon occurs because the sugar molecules occupy spaces between the water molecules, allowing the total volume to remain constant despite the addition of the solute. It highlights the ability of different substances to interact without necessarily increasing the total volume of the mixture.
The mass of both solute and solvent are conserved (sugar water weighs the same as the sugar plus the water), the volume of the solution increases less than the dry volume of the sugar, so the density of the solution is higher than water.
Concentration increases
The addition of 5ml of sugar to 250ml of coffee should increase the total volume to 255ml, not remain at 250ml. Mixing two substances typically leads to an increase in total volume due to the added volume of the sugar.
Nothing. The main concept of dissolving something is that it does NOT add to the volume of the liquid. You can just keep chucking the sugar into the water and the volume will not change (the weight WILL!). ...At least not until you have added over 91g, then no more will dissolve at all. If you keep adding sugar, it will float about and collect at the bottom and the volume will increase with every grain added. It's 91g because Glucose (I assume this is the sugar you refer to) has a water solubility of 91g per litre.
Adding matter to matter with always increase overall volume

The volume increase.
Increase --------------------- It adds mass and in this case that increases volume. Mixing or dissolving of two or more individual components does NOT always produce an increase in volume as volume is determined by the arrangement/bonding in the pure and mixed components. Especially if one component is in vast excess, as with a spoonful of sugar in a glass of water, tighter packing in a mixture can lead to a reduction or no change in volume. In this case my answer is based on educated guess, in turn based on probability.
Salt is dissolved in a smaller volume of water.
The characteristic of matter illustrated by this observation is that sugar dissolves in water, forming a homogeneous mixture without increasing the total volume. This demonstrates the property of solubility, where the sugar molecules are dispersed evenly throughout the water molecules without changing the overall volume of the solution.
The only thing you can add to water to increase its volume is more water.
Yes. Dissolved sugar increase the boiling point.
i agree with the last person who answered this question!!!!! it will surely increase the mass!!!!
