Volume - Units Of Volume, The Volume Of Solids, The Volume Of Liquids And Gases

Volume is the amount of space occupied by an object or a material. Volume is said to be a derived unit, since the volume of an object can be known from other measurements. In order to find the volume of a rectangular box, for example, one only needs to know the length, width, and depth of the box. Then the volume can be calculated from the formula, V = l × w × d.
Volume of most physical objects is a function of two other factors, temperature and pressure. In general, the volume of an object increases with an increase in temperature and decreases with an increase in pressure. Some exceptions exist to this general rule. For example, when water is heated from a temperature of 32°F (0°C) to 39°F (4°C), it decreases in volume. Above 39°F (4°C), however, further heating of water results in an increase in volume that is more characteristic of matter.

The term unit volume refers to the volume of one something: one quart, one milliliter, or one cubic inch, for example. Every measuring system that exists defines a unit volume for that system. Then, when one speaks about the volume of an object in that system, what he or she means is how many times that unit volume is contained within the object. If the volume of a glass of water is said to be 35.…
The volume of solids is relatively less affected by pressure and temperature changes than is that of liquids or gases. For example, heating a liter of iron from 32°F (0°C) to 212°F (100°C) causes an increase in volume of less than 1%, and heating a liter of water through the same temperature range causes an increase in volume of less than 5%. But heating a liter of air …
Measuring the volume of a liquid is relatively straight forward. Since liquids take the shape of the container in which they are placed, a liquid whose volume is to be found can simply be poured into a graduated container, that is, a container on which some scale has been etched. Graduated cylinders of various sizes, ranging from 10 ml to 1 l are commonly available in science laboratories for meas…
