Matter changes from one state to another state on change in _.
Correct answer: B. Pressure
- A. Density
- B. Pressure
- C. Viscosity
- D. All
Explanation
Matter changes from one state to another by change in temperature and pressure. For e.g. solids on heating changes to liquid, liquid on further heating changes to gases. In same manner gases on compression means on applying pressure changes to liquid again.

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.
