(59,63) A compound with a molecular mass of 168 g/mol has an enthalpy of vaporization of 56.8 kJ/mol. At 35°C the vapor pressure is 455torr. a. What is the normal boiling point of the sample? b. A 3g sample of the compound is condensed onto a 155g sample of aluminum at 10°C. Considering only the energy of the condensation of the compound (do not worry about the liquid cooling) what is the new temperature, in °C, of the aluminum? Use the heat capacity of aluminum found in Chapter

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.
