This graph shows how the vapor pressure of three liquids varies with temperature: 900 800 4 700 600 500 400 300 200 octane – pyridine orthoxylene 100 100 110 120 130 140 temperature, °C Use the graph to answer the following questions: Which liquid is the most volatile? most volatile: choose one Which is the least volatile? least volatile: choose one octane: °C What is the normal boiling point of each liquid? Note: your answer must be within 1°C of the exact answer to be graded correct. pyridine: orthoxylene: more Suppose a beaker of pyridine is put inside a sealed tank containing pyridine gas at 112. degree C and 858. torr. After ten minutes, will there be more liquid in tho boakor locc liguid less amount? vapor pressure, torr
States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.
a.) Volatile liquids are those which can easily boil . So they have lower boiling point or Higher vapor pressure.
b.) Normal boiling point is the temperature at which vapor pressure of the liquid is equal to normal atmospheric pressure , which is 760 torr.
c.) To determine the amount , we would check the vapor pressure at given temperature .
