3. Consider the following. There are 2 beakers, both containing the same amount of water at the same temperature. A sugar cube is added to one, and an eraser is added to the other. After 20 minutes, (a)
describe what you would observe in each beaker, (b) identify whether density, rigidity, or fluidity of the
added items (sugar/eraser) increased/decreased/remained the same, and (c) briefly defend your choice.

intermolecular forces are the forces between molecules or particles.

there are two kinds of van der waals forces: weak london dispersion forces and stronger dipole-dipole forces.

in molecule of water there are dipole-dipole forces between negatively charged oxygen from one molecule of water and positively charger hydrogen of another molecule of water.

hydrogen bond is an electrostatic attraction between two polar groups that occurs when a hydrogen atom (h), covalently bound to a highly electronegative atom such as flourine (f), oxygen (o) and nitrogen (n) atoms.
