Enough of a volatile liquid is placed in a closed container to achieve a liquid-vapor equilibrium at a fixed temperature. Liquid that evaporates at room temperature, or vaporizes easily. Air leaves the flask through the pinhole and vapour then fills the flask. The term can also be applied to the phase change from a solid state to vapor, which is called sublimation. Much less energy (in the form of heat) is required to break the intermolecular bonds of a volatile liquid than those of liquids having higher boiling points. Once enough energy is supplied to break apart the bonds between molecules, the molecules are free to expand and escape the liquid surface in the form of a gas.

Volatile just means "easily evaporates.". Colorless, volatile liquid. When it is warm, it is mostly a gas, and when it is cool it is mostly a liquid. Liquid crystal displays (LCDs), ubiquitously used indoors in smartphones, computer monitors, laptops, and televisions, have become an essential aspect of modern life. To measure the relative molecular mass of a volatile liquid The Molar Mass of a Volatile Liquid. Determining the Molar Mass of a Volatile Liquid Introduction In the world of chemistry, it is crucial to have the ability to determine specific properties of unknown substances in order to classify and categorize them. 6058-6067. A) can go from solid to liquid, within a small temperature range, via the application of pressure B) sublimes rather than melts under ordinary conditions C) cannot go from solid to liquid by application of pressure at any temperature D) cannot be liquefied above its triple point E) melts rather than sublimes under ordinary conditions As other answers mention, there is correlation, as flammable liquids are generally less polar and more volatile than polar and less flamable molecules of similar … A substance is said to be volatile if it boils at a low temperature, changing from the liquid to the gas phase. Thermocapillary migration of interfacial droplets. Grigoriev. Scientists commonly use the boiling point of a liquid as the measure of volatility.
