Which of the following is a characteristic property of a liquid?

Question

Examoogle · Accepted Answer

The correct answer is Option C: No definite shape but definite volume. Liquids possess a definite volume because their particles are closely packed, but they do not have a fixed shape as the particles can slide past each other, allowing the liquid to assume the shape of its container.

Step-by-Step Solution & Concepts:
Liquids possess a definite volume because their particles are closely packed, but they do not have a fixed shape as the particles can slide past each other, allowing the liquid to assume the shape of its container.

Working Principle: In a liquid, intermolecular forces are strong enough to keep particles together, giving a constant volume, yet they are weak enough to permit relative movement, so the liquid flows and conforms to the container’s shape.

Key Formulas: $ho = \frac{m}{V}$ — density relating mass and volume

Key Points: Liquids have a fixed volume but no fixed shape.; The shape of a liquid is determined by the container it occupies.

Advantages: Can fill irregular containers easily; Flows to transfer heat or mass efficiently

Disadvantages: Cannot retain shape when poured; Prone to spillage

Applications: Lubrication in engines; Beverages and cooking

Additional Info: Standard density of water at 4°C is $1\,	ext{g/cm}^3$.. Option A describes a solid, Option B contradicts the definition of a liquid, and Option D describes a gas.

Answer: C is correct — liquids have a definite volume but no definite shape.

Exam Tip: Remember the hierarchy: Solids = shape & volume, Liquids = volume only, Gases = neither; this quick rule helps eliminate wrong choices.
