CHEM 1212 Exam Questions and Answers Already Passed Latest Update In terms of their bulk properties, how do liquids and solids differ? How are they similar? - Answers Similar: -Matter composed of atoms, ions, or molecules -Incompressible and have similar densities that are both much larger than those of gases Different: -Liquids have no fixed shape -Solids are rigid In terms of the kinetic molecular theory, in what ways are liquids similar to solids? In what ways are liquids different from solids? - Answers Solids -Tightly packed -Regular pattern -Vibrate in fixed positions -Do not move in relation to another Liquids -close together with no regular pattern -Move past each other -Remain in constant contact In terms of the kinetic molecular theory, in what ways are LIQUIDS similar to GASES? In what ways are liquids different from gases? - Answers Similar: -atoms or molecules are free to move from one position to another Differ: -Particles of a liquid are confined to the shape of the vessel in which they are placed -Gas will expand without limit to fill the space into which it is placed Explain why liquids assume the shape of any container into which they are poured, whereas solids are rigid and retain their shape. - Answers What is the evidence that all neutral atoms and molecules exert attractive forces on each other? - Answers All atoms and molecules will condense into a liquid or solid in which the attractive forces exceed the kinetic energy of the molecules, at sufficiently low temperature.
