    This project was preformed to supply Libretext Authors with videos on General Chemistry topics which can be used to enhance their projects.  Also, these videos are meant to act as a learning resource for all General Chemistry students.

    Water (H2O) is a polar molecule while many gases (O2 & N2) are nonpolar. Because gases do dissolve in water, there must be some kind of intermolecular force between them. The permanent dipole in water causes polarization in the O2 molecule. As the negative side of a water molecule approaches the O2 molecule, the electrons surrounding the O2 molecule are pushed away creating an induced dipole. Now there is an interaction between the negative side of the water molecule and the positive side of the O2 molecule. This is called a Dipole-Induced Dipole intermolecular force.
