1. [9 pts.] A cylinder with a movable piston contains 218 mL of nitrogen gas at a pressure of
1.32 atm and a temperature of 298 K. The piston moves such that the final pressure of gas is
1.55 atm and the final temperature is 335 K. Calculate the final volume in liters.

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.
