Density of Hexane: An Introduction
The density of a substance is defined as its mass per unit volume. In the case of hexane, its density is approximately 0.659 g/cm³ at 20°C. This value is crucial in determining the behavior of hexane under different conditions, such as temperature and pressure. The density of hexane is also influenced by the presence of impurities, which can alter its physical and chemical properties.
Temperature Dependence of Hexane Density
Temperature plays a significant role in determining the density of hexane. As the temperature increases, the density of hexane decreases. This is because the molecules of hexane gain kinetic energy and start moving faster, resulting in an increase in the distance between them. Conversely, as the temperature decreases, the density of hexane increases. This is because the molecules of hexane lose kinetic energy and start moving slower, resulting in a decrease in the distance between them.
| Temperature (°C) | Density (g/cm³) |
|---|---|
| 20 | 0.659 |
| 30 | 0.646 |
| 40 | 0.633 |
Pressure Dependence of Hexane Density
Pressure also plays a significant role in determining the density of hexane. As the pressure increases, the density of hexane decreases. This is because the molecules of hexane are forced closer together, resulting in an increase in the distance between them. Conversely, as the pressure decreases, the density of hexane increases. This is because the molecules of hexane are able to move further apart, resulting in a decrease in the distance between them.
Impurities and Hexane Density
The presence of impurities can significantly affect the density of hexane. Impurities can alter the physical and chemical properties of hexane, resulting in changes to its density. For example, the presence of water can increase the density of hexane, while the presence of other solvents can decrease its density. Understanding the effects of impurities on hexane density is critical in various industrial applications, such as pharmaceuticals and food processing.
Applications of Hexane Density
