Measuring volumes of solids and gases is essential in various areas of science and industry. To do this, it is necessary to use appropriate units that allow correct quantification of these volumes. In this section, we will provide a step-by-step approach to measuring volumes of solids and gases, as well as some useful tools and examples.
Before we start measuring volumes, it is important to note that solids and gases have different properties in terms of their shape and the way they occupy space. For both cases, it is necessary to use appropriate units of measurement. For solids, the cubic meter (m³) is generally used as the standard unit for volume, although other units such as the liter (L) or the cubic centimeter (cm³) can also be used. For gases, it is common to use the cubic meter (m³) or the liter (L) as standard units, the latter being more used in everyday applications.
The first step in measuring the volume of a solid is determining its shape. Depending on whether the solid has a regular or irregular shape, measurement methods may vary. For regularly shaped solids, such as a cube or sphere, mathematical formulas can be used to calculate volume. For example, the volume of a cube is obtained by cubing the length of one of its sides. For irregularly shaped solids, techniques such as water immersion can be used to determine volume based on liquid displacement.
