That solution is 1. synonym for dissolution, except that the product of the solution (or dissolution) process, is also termed a solution, this being a combination of liquid and non-liquid (solid or gaseous) components that exists as a liquid [9]. 2. a homogeneous mixture of two or more components. in ideal solutions, the movement of molecules in charged species are independent of each other; in aqueous solutions charged species interact even at very low concentrations, decreasing the activity of the solutes [22]. 4. the change of matter from a solid or gaseous state to a liquid state by combination with a liquid [10]. 5. the result of such change; a liquid combination of a liquid and a nonliquid substance [10]. see corrosion.?

Cave ventilation is influenced by variations in the CO2-dependent virtual temperature
Abstract:

Dynamics and drivers of ventilation in caves are of growing interest for different fields of science. Accumulated CO2 in caves can be exchanged with the atmosphere, modifying the internal CO2 content, affecting stalagmite growth rates, deteriorating rupestrian paintings, or creating new minerals. Current estimates of cave ventilation neglect the role of high CO2 concentrations in determining air density – approximated via the virtual temperature (Tv) –, affecting buoyancy and therefore the release or storage of CO2. Here we try to improve knowledge and understanding of cave ventilation through the use of Tv in CO2-rich air to explain buoyancy for different values of temperature (T) and CO2 content. Also, we show differences between T and Tv for 14 different experimental sites in the vadose zone, demonstrating the importance of using the correct definition of Tv to determine air buoyancy in caves. The calculation of Tv (including CO2 effects) is currently available via internet using an excel template, requiring the input of CO2 (%), air temperature (oC) and relative humidity (%).
