This graph shows how the vapor pressure of three liquids varies with temperature: 900 800 700 600 500 400. 300. - ethylbenzene 200 octane 100 acetic acid 0. 100 110 120 130 140 temperature, °C Use the graph to answer the following questions: most volatile: choose one Which liquid is the most volatile? Which is the least volatile? least volatile: choose one ethylbenzene: 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. octane: acetic acid: O more Suppose a beaker of octane is put inside a sealed tank containing octane gas at 123. degree C and 818. torr. After ten minutes, will there be more liquid in the beaker, less liquid, or the same amount? O less O the same 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.
