The new dissolves atoms still need some space in the liquid, and most of the time this means that the volume increases. So the mass of the solute is now added to the solvent and because the volume isn’t dependant on the mass of the particles dissolved it won’t change in a way that keeps the density the same.

The increase in temperature causes the kinetic or thermal energy to increase and the molecules become more mobile. The attractive binding energy is reduced and therefore the viscosity is reduced.

Solute almost always changes the volume of final solution.

When sugar is dissolved in water, the volume of the water increases, but not by much. Adding equal volumes of sugar and water together does not double the volume of the water, due to the properties of solutions. When sugar dissolves in water, the sugar molecules take up space between the water molecules.

Tea is a liquid substance so, its particles are not very closely and tightly packed. When we add sugar to it, the sugar particles occupy the spaces between the tea particles and hence the volume of tea does not increase.

Answer: Because sugar dissolve in water and fix into empty space between molecules. The level of water doesn’t change when sugar is dissolved in it as it is soluble in water it occupies space between the 2 molecules of water. Hence it’s level ie it’s volume doesn’t increases.

Second, when the sugar dissolves into individual molecules, the sugar and water molecules can get much closer together, further decreasing the total volume.

As you add sugar to the water, more and more sugar molecules take the available space between water molecules, making the solution more dense.

When sugar is dissolved in water, the volume of the water increases, but not by much. When sugar dissolves in water, the sugar molecules take up space between the water molecules. The mass of the total solution equals the mass of its components, so sugar water is more dense than pure water.

the level of water doesn’t change when sugar is dissolved in it as it is soluble in water it occupies space between the 2 molecules of water. Hence it’s level ie it’s volume doesn’t increases.
