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.

3. Use the table to predict how the molecular surface area affects boiling point. Think about a
sphere-it has the lowest surface area for the given volume. The closer the molecular shape
to a sphere the lower the surface area. Pick two more molecules from the table - with the
similar MM's and similar IMFs but with different surface areas - to illustrate how the surface
area affects bp.

a) Draw structures for the two more molecules, name all molecules, and list the types of
intermolecular forces that are present in each case.
