Acetone (CH3COCH3) is a highly volatile compound, which readily evaporates off when exposed to air. Furthermore, these cause harmful environmental conditions such as global warming and ozone layer depletion. Volatile Substance: Volatile substances readily transfer into the gaseous phase. Therefore, they also have low boiling points. Non-Volatile Memory. Unlike volatile memory, it does not require an electric charge to maintain the storage state. The presence of a solute in a solvent lowers the ability of that particular solvent to evaporate. At a given temperature and pressure, a substance with high volatility is more likely to exist as a vapor, while a substance with low volatility is more likely to be a liquid or solid.

Volatile In chemistry, the term volatile is used to describe substances that have a higher tendency to go into the vaporization phase, even at considerably low temperature. A substance that may transform into gaseous phase directly from solid phase through sublimation is also considered volatile. Volatile compounds also have weaker intermolecular forces such as Van Der Waals forces. However, after evaporation, the non-volatile solute will not appear in the vapour phase of the volatile solvent. This decrease in vapor pressure can be explained by using the entropy differences of the liquid and gas phases along with the position of dissolved particles after the addition of the solute. Some substances such as ammonium chloride, camphor, naphthalene and anthracene are sublime substances. Most organic compounds are volatile.

Reason : Saline hydrides are compounds of hydrogen with most of the p-block elements. We can also use this method for separating liquids having sufficient difference in their boiling points. The key difference between volatile and nonvolatile is that the volatile substances have a tendency to vaporize whereas the nonvolatile substances do not have a tendency to vaporize. Substances Arranged by Increasing Volatility Volatility and Vapor Pressure At the molecular level, particles in liquids have a range of kinetic energies. Web. This is because of the hydrogen bonding between the molecules. In other words, a nonvolatile material exerts a low vapor pressure and has a slow rate of evaporation. Thus, this is the key difference between volatile and nonvolatile acids. Volatile vs Non-Volatile Acids Summary: Difference Between Volatile and Non-Volatile Acids is that Volatile acids are derived from CO2. “Understand What Nonvolatile Means in Chemistry.” About.com Education. Volatile acids are chemical compounds that undergo vaporization rapidly whereas nonvolatile acids are chemical compounds that cannot undergo vaporization rapidly. The volatility of a substance refers to its ability to transfer into the vapour phase from the liquid phase. Sugar (sucrose) and salt (sodium chloride) are nonvolatile solids. These are somewhat harmful to health. We use this method for the purification of liquids which boil without decomposition and contain non-volatile impurities. Figure 2: Mercury, an example of nonvolatile substance. Since it contains metallic bonds, metal mercury ions embedded in a sea of electrons, cannot be easily evaporated and has a very high boiling point and a low vapour pressure. ... Journal of Agricultural and Food Chemistry, 50 (2002), pp. Non-volatile residue (NVR) or non-volatile matter is the soluble, suspended, or particulate material remaining following evaporation of the volatile solvent which contains the material. Unlike volatile memory, NVM does not require its memory data to be periodically refreshed. Dr. Helmenstine holds a Ph.D. in biomedical sciences and is a science writer, educator, and consultant. 6725-6739. N.p., 17 Feb. 2017. Non-volatile memory is typically used for the task of secondary storage or long-term persistent storage. Although both Br3 and Iz ions are known, the F3 ion has not been observed.
