What are the extensive and intensive properties described in this experiment? Which properties would change and which would stay the same if you ran the experiment using 7.5 -ounce cans instead of 12-ounce cans? I need this ASAP

Answer//the law of conservation of mass.;

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.
