Napthalene, C10H8, melts at 80.0°C. If the vapor pressure of the liquid is 10 Torr at 85.8°C and 40 Torr at 119.3°C, and that of the solids is 1 Torr at 52.6°C, calculate а) the AHvap of the liquid, the Tb, and the ASvap at Tp b) the vapor pressure at the melting point c) calculate AHsub of the solid and AHfus. assuming that the melting-point and triple-point temperature are the same,
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.
