Which unit is used to express the volume of a liquid?

• A. Kilogram
• B. Liter
• C. Meter
• D. Mole

Answer: (B)

Volume is the amount of space a substance takes up, and for liquids the standard unit used is the liter. A liter is a unit of volume defined as the space occupied by a cube 10 cm on each side, which equals 1000 cubic centimeters, making it practical for measuring common liquid quantities like water, milk, or juice. The other terms measure different properties: kilograms (or grams) quantify mass, meters measure length, and moles count a specific amount of substance. For smaller liquid amounts, milliliters are used (1 L = 1000 mL), while larger volumes might use liters or cubic meters in different contexts.
