Use the observation in the first column to answer the question in the second column. observation The enthalpy of vaporization of Substance C is bigger than that of Substance D. At 1 atm pressure, Substance A boils at 117. °C and Substance B boils at 82. °C. At -2 °C, Substance E has a vapor pressure of 109. torr and Substance F has a vapor pressure of 59. torr. question At any temperature where both substances are liquid, which has the higher vapor pressure? Substance C Substance D Neither, C and D have the same vapor pressure. O It's impossible to know without more information. Which has a higher enthalpy of vaporization? Substance A Substance B Neither, A and B have the same enthalpy of vaporization. It's impossible to know without more information. Which has a higher enthalpy of vaporization? Substance E Substance F Neither, E and F have the same enthalpy of vaporization. It's impossible to know without more information. Y 5
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.
We know, at thermodynamic temperature, the enthalpy of vaporization of a liquid is proportional to its boiling point. Which means higher the enthalpy of vaporization of a liquid higher is the boiling point of it.
And we know, higher the vapor pressure of a liquid lower is its boiling point.
