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
Atomic, molecular, and optical physics system of electrons and an atomic nucleus, while molecular physics is the study of the physical properties of molecules. The term "atomic physics" is often associated with nuclear power and nuclear bombs, due to the synonymous use of "atomic" and "nuclear" in standard English. However, physicists distinguish between atomic physics — which deals with the atom as a system consisting of a nucleus and electrons — and nuclear physics, which considers atomic nuclei alone. The important experimental techniques are the various types of spectroscopy. Molecular physics, while closely related to atomic physics, also overlaps greatly with theoretical chemistry, physical chemistry
