Gases, Liquids, and Solids ± Gases, liquids and solids are all made up of atoms, molecules, and/or ions, but the behaviours of these particles differ in the three phases. ± Particles in a: ² _________ are well separated with no regular arrangement. ² __________ are close together with no regular arrangement. ² __________ are tightly packed, usually in a regular pattern. ± Particles in a: ² __________ vibrate and move freely at high speeds. ² __________ vibrate, move about, and slide past each other. ² ___________ vibrate (jiggle) but generally do not move from place to place.

does not flow easily rigid - particles cannot move/slide past one another flows easily particles can move/slide past one another flows easily particles can move past one another not easily compressible little free space between particles not easily compressible little free space between particles compressible lots of free space between particles retains a fixed volume and shape rigid - particles locked into place assumes the shape of the part of the container which it occupies particles can move/slide past one another assumes the shape and volume of its container particles can move past one another solid liquid gas Some Characteristics of Gases, Liquids and Solids and the Microscopic Explanation for the Behavior

Properties of liquids ± Liquids retain volume but not shape. ± Liquids are practically non-compressible because the molecules are already close together. ± Liquids have much higher densities than gases, and usually (water is a notable exception) have lower densities than the corresponding solid (Explain !). ± Liquids exhibit a resistance to flow called ___________ . Viscosity depends on temperature (higher temperature reduces viscosity) and the nature of the liquid . ± Liquids exhibit a resistance to an increase in their surface area called ________________ (an older, but still commonly-used term is _________________ ). ± Surface free energy, like viscosity, depends on temperature (higher temperatures reduce surface free energy) and the nature of the liquid . ± ______________ and ______________ are related to the forces of attraction between molecules.

What kinds of materials form liquids at room temperature ± Three factors determine whether a substance is a gas, a liquid, or a solid at room temperature and atmospheric pressure: (1) the ___________ of the bonds between the particles that form the substance (2) the _________________________ of these particles (3) the ___________ of these particles
