4 Random motion of gas particles causes a gas to expand until it fills its container. density of a gas decreases as it is gas can flow into a space occupied by another gas. diffusion of a gas is caused by the random motion of the particles of the gas. gas particles diffuse less rapidly than do heavier gas particles. effusion. a gas escapes through a tiny opening into a vacuum. s law of effusion states that the rate of effusion for a gas isdirectly related to the square root of its molar mass. falsetruefalsetruetruefalsetruetrueTempe ratureKE 51/2mv2kineticelasticrandomforcessmallmo tionSTUDY GUIDE FOR CONTENT MASTERYCHAPTER13 Copyright Glencoe/McGraw-Hill, a division of the McGraw-Hill Companies, GUIDE for CONTENT MASTERY Answer KeyChemistry: Matter and ChangeT195 NameDateClass76 Chemistry: Matter and Change Chapter 13 STUDY GUIDE for CONTENT MasterySection and SolidsIn your textbook, read about liquids and the space at the left, write trueif the statement is true.
