2.3 Phase Changes CP

Draw

The density of oxygen at 1 atm and various

temperatures is given in the table. Plot the data and circle the

temperature(s) at which oxygen changes from liquid to gas.

Draw

The table shows the atomic radii and boiling

points of five halogens that experience intermolecular dispersion

forces. Plot the boiling point vs. the atomic radius and use the

resulting pattern to predict the boiling point

of astatine.
