Arrange the gases in increasing order of the number of atoms that make up its molecule from left to right. CH4 CO2 C2H2 Br2. For a given element, in which state of potential energy would you expect to have (a) the greatest and (b) the least amount of potential energy? Explain you answers in terms of the chemical energy holding atoms together.

Answer/// he concludes that the atom particles can be broken due to the paddle wheel being moved by particles coming out of the metal;

Vander waals forces are inter molecular bonds that exist within molecules of the same substance. a water molecule is made up of oxygen and hydrogen atoms which share electrons between each other. the vander waals forces are forces that exist between multitude of different  molecules of water. dipole dipole forces is the type of vander waals force that exist in water. the oxygen atom which is more electronegative pulls the shared electron closer to itself thus generating a partial negative charge while the hydrogen acquire a partial positive charge. these two different charges causes attraction to occur in water molecules.
