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
Education sector responses to substance abuse sexual health, nutrition and bullying. In a curriculum, substance use prevention education is usually and most appropriately accommodated in a health-related subject area (variously termed healthy active living, health and family living, health and physical education, personal and social skills education, health and career education, life-skills education, etc.). Many schools choose also to supplement or replace the standard life-skills or other health-related curriculum with a manualized programme, i.e., a programme standardized through the creation of manuals and protocols for those who implement it. This has been shown by research to be effective in preventing substance use later in life and/
