Solid-Vapour Equilibrium
This section deals with the solubility of solids in gases. The phase equilibria consideration here are relatively straightforward as the solubility of gases in solids is usually negligible. Therefore, the solid phase may be considered as pure; all non-ideality in the system therefore, derives from that of the gas phase. In the following analysis we, thus, consider that a pure solid phase (1) co-exists in equilibrium with a vapour-phase mixture of the gas (or solvent, 2) and the solute (i.e., 1). The phase equilibria relation for the component 1 may be written as:
....(9.78)
A relation of the form of eqn. 6.119 used for pure liquid phase fugacity calculation may be employed to compute the fugacity of a pure solid at the temperature T and pressure P of the system.
....(6.119)
For a pure solid the corresponding equation is:
....(9.79)
Here V1S is the molar volume of the solid, and P1sat is the vapour-phase saturation pressure for the solid solute at the given temperature. Now for the vapour phase fugacity of the solute on has:
....(9.80)
Thus using eqns. 9.78 – 9.80 one obtains:
....(9.81)
The above equation may be written in a compressed form as follows:
....(9.82)
Where,
....(9.83)
The term E is called the enhancement factor. The vapour pressure P1sat of solids is typically very low (~ 10-5 – 10-3 bar), hence 
Further if the system pressure is also low or as 
Thus, on inspecting eqn. 9.82, it is evident that under such a condition E = 1. The corresponding solubility y1 is termed the ideal solubility. At high pressures (with 
, the exponential Poynting factor tends to be greater than one, and the values of 
are lower than unity. As a result, the factor E typically is higher than one. The enhancement factor, therefore, provides a measure of the degree to which pressure augments the solubility of the solid in the gas phase.

FAQs on Solid Vapour Equilibrium - Additional Documents & Tests for Civil Engineering (CE)
| 1. What is solid-vapour equilibrium in civil engineering? |  |
| 2. Why is solid-vapour equilibrium important in civil engineering? | |
Solid-vapour equilibrium is important in civil engineering as it affects various processes and materials. It is crucial in the design and construction of structures to ensure that materials such as concrete or asphalt reach the desired moisture content. Understanding the equilibrium helps prevent issues such as shrinkage, cracking, or excess moisture that can compromise the integrity and durability of the structure.
| 3. What factors influence solid-vapour equilibrium in civil engineering? | |
Several factors influence solid-vapour equilibrium in civil engineering. The temperature and relative humidity of the environment play a significant role in determining the equilibrium conditions. The type and properties of the solid material, such as its porosity and surface area, also affect the equilibrium. Additionally, external factors like air movement and exposure to sunlight can impact the equilibrium state.
| 4. How can solid-vapour equilibrium be controlled in civil engineering projects? | |
Solid-vapour equilibrium can be controlled in civil engineering projects through proper moisture management techniques. This includes using waterproofing measures to prevent excessive moisture ingress or employing moisture barriers to reduce moisture evaporation from the solid material. Additionally, controlling the temperature and humidity levels in the environment can help maintain the desired equilibrium conditions.
| 5. What are the consequences of a disrupted solid-vapour equilibrium in civil engineering? | |
Disruption of solid-vapour equilibrium in civil engineering can lead to various issues. If the solid material becomes too dry, it may result in shrinkage, cracking, and reduced strength. On the other hand, excessive moisture can cause swelling, deformation, and increased susceptibility to corrosion or microbial growth. It is essential to maintain the proper equilibrium to ensure the long-term performance and durability of civil engineering structures.
