Which list comprises types of physical measurements?

Which list comprises types of physical measurements?

• A. Length, mass, volume, temperature, and time.
• B. Color, texture, taste, odor.
• C. Energy, force, momentum, acceleration.
• D. Pressure, density, viscosity without temperature.

Answer: (A)

Measurable quantities in science are the properties you can assign numbers to using standardized units. The list length, mass, volume, temperature, and time covers the main physical dimensions that scientists routinely quantify with instruments. Length is checked with rulers or calipers, mass with balances or scales, volume with graduated cylinders or volumetric flasks, temperature with thermometers, and time with clocks or timers. Each has standard units like meters, kilograms, liters (or cubic meters for volume), kelvin or Celsius, and seconds, which makes them universal measurements. The other options mix qualitative attributes—color, texture, taste, odor—that aren’t numerical measurements in the same consistent way. And while energy, force, momentum, and acceleration can be measured, they aren’t grouped with basic measurement types in the way length, mass, volume, temperature, and time are, plus one list omits temperature entirely, making it incomplete as a set of common physical measurements.
