During which process empty spaces between particles become minimum ?
Correct answer: B. condensation
- A. ionization
- B. condensation
- C. fusion
- D. evaporation
Explanation
During condensation, particles change from the gas state to the liquid state and move closer together, so the empty spaces between them decrease. Students may choose fusion because it is also a phase change, but melting generally increases particle spacing rather than minimizing it.

About Properties of Liquids
Liquid behavior depends on intermolecular forces, which produce surface tension, viscosity, capillary action and a definite volume without a fixed shape. The topic also covers vapor pressure, evaporation, boiling point and the effect of temperature and external pressure, while distinguishing evaporation at the surface from boiling throughout the liquid.
