Which of the following is a property of liquids?
Liquids are rigid.
Liquids have a fixed shape.
Liquids do not have a fixed volume.
The rate of diffusion of liquids is higher than that of solids.
The rate of diffusion of liquids is higher than that of solids.
Liquids are a state of matter characterized by their ability to flow, which distinguishes them from rigid solids. Unlike solids, liquids do not have a fixed shape and take the shape of the container they occupy, although they maintain a fixed volume.

Think of water poured into a glass; it immediately conforms to the shape of the glass, unlike an ice cube (solid) which retains its own shape regardless of the container.
The particles in a liquid have more kinetic energy than those in a solid, allowing them to overcome some intermolecular forces of attraction. This enables the particles to slide past one another, resulting in fluidity and the ability to diffuse into other liquids or gases at a higher rate than solids.
Liquids have a definite volume but no fixed shape.
Liquids are considered fluids because they can flow.
Intermolecular forces in liquids are weaker than in solids but stronger than in gases.
Diffusion in liquids is faster than in solids because particles are not locked in a rigid structure.

| Feature | Solids | Liquids |
|---|---|---|
State Property | Rigid | Fluid |
Rigidity is the tendency of a substance to resist a change in shape, a key feature of solids.
Option A is incorrect because liquids are fluids, not rigid.
Option B is incorrect because liquids take the shape of their container.
Option C is incorrect because liquids possess a fixed volume at a given temperature and pressure.
D is correct тАФ The rate of diffusion of liquids is higher than that of solids because liquid particles have enough kinetic energy to move and spread out more freely.
Always remember: Solids = Fixed shape/volume, Liquids = Fixed volume/variable shape, Gases = Variable volume/variable shape.
