Oh my gosh this is so ironic!! Last night for the science fair I got BEST IN FAIR for a project on this!!! Here is a copy of my abstract:
Molecules in the liquid state have strong intermolecular attractive force. When those forces are between like molecules, they are referred to as cohesive forces. For example, the molecules of water droplet are held together by cohesive forces, and the especially strong cohesive forces at the surface constitute surface tension. Surface tension is caused by water molecules. Water molecules are unevenly charged o they are attracted to each other. So that?s why the penny can hold the most water out of the other substances.
All atoms and molecules have electromagnatism, but not all are magnetic. In order to be magnetic, they must be able to align the atoms based upon a magnetic field, and water molecules to not do this. In fact, I dont think liquids can be magnetic.
