Uranium is used in nuclear reactors and is a rare element on earth. Uranium has three common isotopes. If the abundance of ²³⁴U is 0.01%, the abundance of ²³⁵U is 0.71%, and the abundance of ²³⁸U is 99.28%, what is the atomic weight of uranium?

False, as a substance changes from a solid to a liquid and from a liquid to a gas the molecules get farther apart from each other

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.
