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)Draw the Naphthalene Phase Diagram[MM= 128.2[g/mol]], add the development used to obtain the different values.
Numerically indicate your triple point, and sketch the vapor, liquid and solid zones, with the following information:
-The critical point of naphthalene occurs at 300 [° C] and 13.15 [atm]
-The fusion enthalpy is 16.9 [kJ / mol].
Also, consider that the densities of the solid and the liquid at the triple point temperature are:
Ps=249[kg/m3] and Pl=1162[kg/m3]respectively. The solid vapor curve has been parameterized as: Ln P=-8600/T + 30.69 Where the pressure is in [Pa] and the temperature in [K].
