Volatility (chemistry) vapor pressure chart (right hand side) displays the vapor pressures dependency for a variety of liquids as a function of temperature. For example, at any given temperature, chloromethane (methyl chloride) has the highest vapor pressure of any of the liquids in the chart. It also has the lowest normal boiling point (−24.2 °C), which is where the vapor pressure curve (the blue line) intersects the horizontal pressure line of one atmosphere (atm) of absolute vapor pressure. Volatility (chemistry) In chemistry and physics, volatility is quantified by the tendency of a substance to vaporize. Volatility is directly related to a substance's
Comparison of chemistry and physics experimental techniques caught up. In chemistry, the role of theory historically has been a retrospective one, summarizing experimental data and predicting the outcome of similar experiments. However, with the increasing power of computational methods in chemistry, it has become possible to predict whether a hypothetical compound is stable or not before experimental data is available. In a typical undergraduate program for physics majors, required courses are in the sub-disciplines of physics, with additional required courses in mathematics. Because much of the insight of physics is described by differential equations relating matter, space, and time (for example Newton's law of motion
