Final answer:
The volume of liquids is measured using tools like a graduated cylinder, while the volume of regular solids is calculated from their dimensions. Irregular solids' volume is measured by water displacement. The density of these substances, which relates to their volume, is also a significant measure, reported in g/cm³ for solids and liquids and g/L for gases.
Step-by-step explanation:
The volume of liquids and solids is measured differently due to their distinct physical properties. For liquids, a common measuring device is a graduated cylinder, which provides marked measurements for volume. Alternatively, a pipet or burette might be used for precise volume measurements in chemical solutions. As for regular solids, their volume can be calculated using their geometric dimensions; for example, a rectangle's volume is the product of its length, width, and height, marked as V = length × width × height. A cube's volume would be the cube of its edge length (V = edge length³).
For irregularly shaped solids, one can measure volume via water displacement, which is the principle that an object displaces a volume of water equivalent to its own when submerged. The density of solids and liquids, often given in grams per cubic centimeter (g/cm³), is related to volume and is especially important for identifying or characterizing substances. For gases, that have a much lower density, the unit grams per liter (g/L) is used.
To measure the volume of an object, the unit of measurement might be cubic centimeters (cm³) or liters (L), depending on the size of the object and the precision required. A liter is equal to 1,000 cubic centimeters, and this unit is convenient for laboratory measurements. The choice of measuring tool, like a graduated cylinder for small volumes of liquid in chemical solutions, is essential for accurate volume determination.
