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 Statistics (United States Department of Labor), there are 80,000 chemists and 17,000 physicists working in the United States as of May 2010. In addition, 21,000 chemists and 13,500 physicists teach in high school. Chemistry is the only science that has an entire industry, the chemical industry, named after it, and many chemists work in this industry, in research and development, production, training, or management. Other industries employing chemists include the petroleum, pharmaceutical, and food industry. While there is no industry named after physics, many industries have grown out of physics research, most notably the semiconductor and electronics industry. Physicists are
