Atmospheric pressure on the peak of Mt. Everest is 0.197 atm, which is why climbers need to bring oxygen tanks for the last part of the climb. If a climber carries a 10.00 L tank with an internal gas pressure of 3.040 x 10* mm Hg what
will be the volume of the gas when it is released from the tank at the top of the mountain?

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.
