Term | Definition |
Kinetic-Molecular Theory | explains the behavior of gases, liquids and solids; can be explained by the process of condensation... biggest difference between gases and liquids is the distance between the particles |
Gases and Liquid | the two phases that can change positions with other particles |
Inter-molecular Forces | a force between particles are stronger in gases than in solids |
Vaporization | the process by which a liquid changes to a gas and the process by which a solid changes to a gas |
Evaporation | The process by which particles escape from the surface of a non boiling liquid and enter the gas state |
High Kinetic Energy | causes particles in a liquid to escape into a gas state |
A Solid | what forms when the average energy of a substance's particles decreases |
Triple Point | the point of a substance is the temperature and pressure conditions at which states of coexist at equilibrium |
Sublimation | the process of a substance changing from a solid to a vapor without passing through the liquid stage |
Fluidity | substance can flow and thus take the shape of the container |
Freezing | when kinetic energy drops too low, transitional motion is decreased and an orderly arrangement without flow occurs |
Molecular Covalent | common gases and liquids are all covalent |
Network Covalent | are all non metals, bonded infinitely in all direction, making one giant molecule |
Ionic | are made of metal cation and nonmetal anions in crystal arrangement; very strong bonds |
Metallic | are just metal ions with a sea of electrons flowing around them, often just one pure metal |
Critical Temperature | the highest temperature at which it is possible for the substance to exist, as a liquid |
Critical Pressure | the lowest amount of pressure you must apply to liquefy it at that temperature well below STP, it is referred to as "permanent gas" |
Iondon Dispirtion | found in all molecules, weakest temporary induced dipoles, |
Dipole Dipoles | stronger, between pos and neg ends of adjacent molecules, raises the boiling and melting point |
