Condensed States of Matter
1. Explain how the kinetic-molecular theory accounts for the physical properties of solids and liquids.
2. Describe the different types of intermolecular forces and explain how the influence the properties of liquids and solids.
Although the Kinetic-Molecular theory was used primarily to explain the actvity and properties of gases, it can also be used to describe the condensed states of solids and liquids.
1st look at the properties of different phases of matter.
According to the Kinetic-Molecular theory, the state of a substance depends on the attractive forces between the molecules of the substance. There are three basic types.
1) Intramolecular forces
Both ionic and covalent bonds are formed in an attempt to satisfy the noble gas (octet) rule of 8 valence electrons in the outermost energy shell.
2) Intermolecular Dispersion Forces (dipole forces)
Induced Dipole Forces:
