30. The enthalpy of vaporization of a certain liquid is found to be 14.4 kJ/mol at 180 K its normal boiling point. The molar volumes of the liquid and vapor at eh boiling point are 115 cm³/mol and 14.5 L/mol respectively. Estimate the dp/dT from the Clapeyron equation. (+5.56E3 Pa/K)
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.
