Distillation is effective because acetone and water have sufficiently different boiling points. Acetone boils at about 56 °C, while water boils at 100 °C, allowing acetone to vaporise first and separate.

If blood behaved like a true suspension, its larger particles would settle when left undisturbed. In blood, the dispersed phase consists of blood cells and the dispersion medium is plasma, remaining dispersed throughout.
Option (iii) is correct. Assertion A is true because transparent solutions do not show the Tyndall effect. Reason R is false because solution particles are smaller than 1 nm, not larger than 100 nm.
Evaporation is a surface phenomenon in which liquid changes into vapour from its surface below the boiling point. Boiling occurs throughout the liquid at its boiling point and produces vapour rapidly throughout it.
Chapter 5 “Exploring Mixtures and their Separation” explains types of mixtures and methods of separation. It helps me understand filtration, evaporation and distillation and how different substances are separated in daily life.
