Solution
A) A liquid has definite volume but not a definite shape. B) The process of change of a substance from the liquid state to its gaseous state at a particular temperature is called boiling or vaporization. C) A fluid exerts pressure in all directions. D) A molecule having more than two atoms is called a polyatomic molecule. E) Solids are rigid and they have a definite shape. F) Gases do not show the property of rigidity.
Q 2) PROPERTY SOLID LIQUID GAS PRESSURE - Solids do not exert pressure unless force is applied. Liquids exert pressure evenly in all directions. Gases exert pressure evenly in all directions. RIGIDITY - Solids are rigid. Liquids are not rigid. Gases are not rigid. EXPANSION ON HEATING - Solids expand very little on heating. Liquids expand more than solids but less than gases. Gases expand the most on heating. INTERMOLECULAR FORCES - Strong in solids. Moderate in liquids. Weak in gases. FLUIDITY - Solids are not fluid. Liquids are fluid. Gases are fluid.
Q 3) A) Cohesive force - It is the force of attraction between identical molecules. B) Adhesive force - It is the force of attraction between different molecules. C) Intermolecular force of attraction - It is the force of attraction between molecules of a substance.
Q 4) SOLID - Molecules are closely packed, definite shape and volume, high density, low compressibility, does not flow. GAS - Molecules are far apart, no definite shape or volume, low density, high compressibility, flows easily.
Note: I'm unable to draw the molecular model here as this is a text-based platform.
