Question

The three states of matter are solid, liquid and gas. Which of the following statement is/are true about them

[AIIMS 1991]

• A. Gases and liquids have viscosity as a common property
• B. The molecules in all the three states possess random translational motion
• C. Gases cannot be converted into solids without passing through the liquid phase
• D. Solids and liquids have vapour pressure as a common property

Answer 1

The correct option is A

Gases and liquids have viscosity as a common property

Both gases and liquids possess fluidity and hence viscosity molecules in the solid state do not have translational motion.
