Question

in a expirement, lydia added 50 grams of sugar to 200 milliliters of water. She stirred the mixture, and the sugar eventually dissolved into the water and couldn’t be seen. The volume of the solution increased, but there was no noticeable change in color, odor, or temperature. Which statement best describes what happened in Lydia’s experiment?

Answer 1

The addition of sugar in water and disappearing of the solid in water is due to the high solubility of the solid that is sugar in water. As it is seen in the experiment there will be no change of the solution except increasing of the volume. But if one look the solution from its density state, then there will be a remarkable change. The fact can be described in terms of density only. The density of the normal water and sugar added water will be different.

The density of the sugar added water will be more than the normal water. The density of a liquid depends upon its mass and volume. The definition of density is the mass of a material per unit of its volume. Here due to addition of 50 grams of sugar the mass will be increase and also its volume as a result the density will also increase.
