Document Summary
Chapter 11 liquids, solids, and intermolecular forces. 11. 2 solids, liquids, and gases: a molecular comparison. The densities of liquid (0. 998) and solid (0. 917) are greater than the density of gas (5. 90*10-4). This is due to the fact that the molecules of solid and liquid are closely packed together however on the other hand gas molecules have a lot of distance between one another. Water is in gaseous state at 100 c, liquid at 20 c, and solid at 0 c. Thermal energy overcomes the intermolecular forces in liquids and this allows them to more around one another. This is not possible in solids; they are locked in position and are only able to vibrate. Solids and liquids cannot be easily compressed since there is not much space between the particles but in gas since there is a large distance between the molecules it can be compressed.
