kaasuhöyryseos

A kaasuhöyryseos, or gas-vapor mixture, refers to a thermodynamic state where a substance exists as both a gas and a vapor simultaneously within a single phase. This occurs at temperatures and pressures where the substance is at its boiling point. In such a mixture, there is an equilibrium between the liquid phase and the gaseous phase. The vapor portion consists of molecules that have escaped from the liquid surface due to sufficient kinetic energy, while the remaining liquid is in a state of continuous vaporization and condensation.

The composition and properties of a kaasuhöyryseos are dependent on the specific substance and the prevailing thermodynamic conditions. For instance, at the boiling point of water at standard atmospheric pressure, water exists as a kaasuhöyryseos, commonly referred to as steam. This mixture is crucial in many industrial processes, such as power generation in steam turbines and various chemical engineering operations. Understanding the behavior of gas-vapor mixtures is fundamental in fields like thermodynamics, fluid mechanics, and material science. The saturation pressure of a substance at a given temperature represents the pressure at which its liquid and vapor phases can coexist in equilibrium.
