The quality of having a low boiling point or subliming temperature at ordinary pressure or, equivalently, of having a high vapor pressure at ordinary temperatures.



the property of liquid and solid substances of passing into the gaseous state. Volatility is measured by the concentration of saturated vapor for a substance at a particular temperature; it is expressed in milligrams per cu m or milligrams per liter and is calculated using the equation of state for ideal gases. The volatility of a substance increases with increasing temperature because of an increase in its saturated vapor pressure. In thermodynamics, “volatility” is also used in place of “fugacity.”
