Down: 1) the process in which vaporization occures only at the surface of a liquid2) the movement of one material through another froman area of higher concentration to an area of lower concentration3) the attractions between appositly charged regions of polar molecules4) describes the behavior of gases in terms of particles in motion; makes several assumptions about size, motion, and energy of gas particles5) the energy required to increase the surface area of a liquid by a given amount; results from an uneven distrubution of attractive forces6) the weak forces resulting from temporary shifts in the density of electrons in electron clouds7) the temperature at which a liquids vapor pressure is equal to the external or atmospheric pressure8) the teperature at which a liquid is converted into a crystalline solid9) the energy releasing process by which a sucstance changes from a gas or vapor to a solid without first becoming a liquid10)  the smallest arrangement of atoms in a crystal latice that has the same symmetry as the whole crystal; a small representative part of whole part12) collision in which no kinetic energy is lost; kinetic energy can be trasfered between the colliding particles, but the total kinetic energy of the two particles remain the same13) a compound, such as soup, that lowers the surface tension of water by disrupting hydrogen bonds between water molecules; also called a surface active agent14) a solid wgose atoms,ions, or molecules are arranged in an orederly, geometric, three dimentional structure17) a measure of the average kinetic energy of the particles in a sample of matter20) the energy-releasing process by which a gas or vapor becomes a liquid24) an instrument that is used to measure atmospheric pressure Across: 9) states that the total pressure of a mixture of gases is equal to the sum of the pressures of all the gases in the mixture11) states that the rate of effusion for a gas is inversely proportional to the square root of its molar mass15) a measire of the resistance of a liquid to flow, which is affected by size and shape of particles, and generally increses as the temperature decreses and as intermolecular forces increase16) the point on a phase diagram representing the temp. and pressure at which the 3 phases of a substance can coexist18) a graph of pressure vs temperature that shows which phase a substance exists in under different conditions of temperatures and pressure19) the SI unit for pressure; one pascal is equal to a forve of one newton per square meter21) one of two or more forms of an element with different stuctures and properties when they are in the same state-solid, liquid, or gas22) a solid in which particles are not arranged in a regular, repeating pattern that often is formed when molten material cools too quickly to form crystals23) the energy requiring process by which a liquid changes to gas or vapor25) a strong dipole-dipole attraction between molecules that contain a hydrogen atom bonded to a small, highly electronegative atom26) forve applied per unit area27) for a crystalline soldi, the temperature at which the forces holding a crystal lattice together are broken and it becomes a liquid28) the pressure exerted by a vapor over liquid29) the unit that is often used to report air pressure
