For example, we usually measure the volume of a liquid sample with pipettes, burets, graduated cylinders, and volumetric flasks (Figure \(\PageIndex{1}\)), whereas we usually measure the mass of a solid or liquid substance with a balance (Figure \(\PageIndex{2}\)).
Describe the properties and units of length, mass, volume, density, temperature, and time. Recognize the common unit prefixes and use them to describe the magnitude of a measurement. Describe and calculate the density of a substance.
We can derive many units from the seven SI base units. For example, we can use the base unit of length to define a unit of volume, and the base units of mass and length to define a unit of density. Volume. Volume is the measure of the amount of space occupied by an object. The standard SI unit of volume is defined by the base unit of length .

Chapter 1: Essential Ideas. 1.4 Measurements. Learning Outcomes. Explain the process of measurement. Identify the three basic parts of a quantity. Describe the properties and base units of length, mass, volume, density, temperature, and time. Memorize base SI unit prefixes.
Every measurement provides three kinds of information: the size or magnitude of the measurement (a number); a standard of comparison for the measurement (a unit); and an indication of the uncertainty of the measurement.

Apr 8, 2024 · V = x · y · z. We say, therefore, that volume has the dimensions of length-cubed: dim.V = L 3. Thus the units of volume will be m 3 (in the SI) or cm 3, ft 3 (English), etc. Moreover, any formula that calculates a volume must contain within it the L 3 dimension; thus the volume of a sphere is 4/3 π r3.
