In chemistry and physics, volatility is the tendency of a substance to vaporize. Volatility is directly related to a substance's vapor pressure. At a given temperature, a substance with higher vapor pressure vaporizes more readily than a substance with a lower vapor pressure.
The term is primarily written to be applied to liquids; however, it may be used to describe the process of sublimation which is associated with solid substances, such as dry ice (solid carbon dioxide) and ammonium chloride, which can change directly from the solid state to a vapor without becoming liquid.
The vapor pressure of a substance is the pressure at which its gas phase is in equilibrium with its condensed phases (liquid or solid). It is a measure of the tendency of molecules and atoms to escape from a liquid or a solid. A liquid's atmospheric pressure boiling point corresponds to the temperature at which its vapor pressure is equal to the surrounding atmospheric pressure and it is often called the normal boiling point.
Chemistry is a branch of physical science that studies the composition, structure, properties and change of matter. Chemistry includes topics such as the properties of individual atoms, how atoms form chemical bonds to create chemical compounds, the interactions of substances through intermolecular forces that give matter its general properties, and the interactions between substances through chemical reactions to form different substances.
Chemistry is sometimes called the central science because it bridges other natural sciences, including physics, geology and biology. For the differences between chemistry and physics see Comparison of chemistry and physics.
Scholars disagree about the etymology of the word chemistry. The history of chemistry can be traced to alchemy, which had been practiced for several millennia in various parts of the world.
The word chemistry comes from the word alchemy which was an earlier set of practices that encompassed elements of chemistry, metallurgy, philosophy, astrology, astronomy, mysticism and medicine. It is often seen as linked to the quest to turn lead or another common starting material into gold. Alchemy, which was practiced around 330, is the study of the composition of waters, movement, growth, embodying, disembodying, drawing the spirits from bodies and bonding the spirits within bodies (Zosimos). An alchemist was called a 'chemist' in popular speech, and later the suffix "-ry" was added to this to describe the art of the chemist as "chemistry".

Ionic compounds tend to be non-volatile since ionic bonds are very strong and require lots of energy to break. Ionic compounds normally dissolve in water since the energy released when water bonds to the ions is enough to break the ionic bonds.
Introduction to distillation, vapor pressure, and volatility from Educator.com’s Organic Chemistry class. Want more video examples? Our full lesson includes in-depth explanations with even more worked out examples. ►See the entire syllabus at http://www.educator.com/chemistry/organic-chemistry/starkey/?utm_source=YT&utm;_medium=SEO&utm;_campaign=OCHEMYT In this video, we'll give an introduction to distillation. You'll learn about simple distillation, fractional distillation, vapor pressure, and volatile liquid. Specifically, we'll talk about how to separate a liquid from a nonvolatile contaminant.

Volatile molecules turn into a gas easily (that is they have weak intermolecular forces that can be broken with small amount of energy). Molecules that are soluble in water (which is polar) will also be polar.

CORE LO: • Describe the differences in volatility, solubility and electrical conductivity between ionic and covalent compounds EXTENDED LO: • Explain the differences in melting point and boiling point of ionic and covalent compounds in terms of attractive forces SC: • Remember that ionic compounds are giant lattice structures with many strong ionic bonds that hold the ions in place and mostly form solids. This makes them less volatile (higher mp/bp)(A*). Ionic compounds are usually soluble in water. Ionic compounds do not conduct electricity in solid form because the ions are in fixed positions in the lattice structure. Ionic compounds conduct electricity when become molten or are soluble because of free-moving ions(C). • Remember that covalent compounds are usually molecules in gaseous f...

Alcohol & Distilleries Documentary | The Process of Distillation - Documentary TV (Official) Distillation is a process of separating the component substances from a liquid mixture by selective evaporation and condensation. Distillation may result in essentially complete separation (nearly pure components), or it may be a partial separation that increases the concentration of selected components of the mixture. In either case the process exploits differences in the volatility of mixture's components. In industrial chemistry, distillation is a unit operation of practically universal importance, but it is a physical separation process and not a chemical reaction.

How often do stocks actually fall within expected range? See more options trading videos: http://ow.ly/MZDKN Today, Tom Sosnoff and Tony Battista are joined by Mike "Dr. Data" Rechenthin, PhD from the Research Team as he explains how fear in the market often causes options to become overpriced, thus causing the stock's expected move to exaggerate the actual price move. Using the formulas from our last "Skinny on Data Science", Dr. Data creates a large backtest to determine how often stocks actually fall within the expected range. The results confirm our strategy of selling premium and explains why it provides us with an edge. Math is the most feared four-lettered word around, even to Tom and Tony. Luckily the well dressed Dr. Data is here to show how to tame the beast and even use it ...
GISS Lunch Seminar: Nov. 6, 2013 Kostas Tsigaridis An AeroCom intercomparison exercise on organic aerosol global modeling Slides available at http://www.giss.nasa.gov/meetings/lunch/2013b/20131106-Kostas-Tsigaridis.pdf Abstract: Comparisons of individual models with organic aerosol (OA) measurements have shown a large underestimation of the OA component by models. The formulations used by individual models are very different, since OA simulations have many degrees of freedom due to the missing knowledge on the behavior and fate of both primary OA (POA) and secondary OA (SOA) in the troposphere. On top of that, several assumptions need to be made and are translated to model tuning parameters that vary greatly between models. Trying to bridge the gap between models and observations, seve...
