Unformatted text preview: It is important to recognize that the volume of a gas (at constant P and T) depends only on the number of gas particles present. The individual volumes of the particles are not a factor because the particle volumes are so small compared with the distances be-tween the particles (for a gas behaving ideally). Mixture of Gases (Dalton's Law) The observation that the total pressure exerted by a mixture of gases is the sum of the pressures of the individual gases is expected because the KMT assumes that all gas par-ticles are independent of each other and that the volumes of the individual particles are unimportant. Thus the identities of the gas particles do not matter. L ::2 Increase volume to return to original pressure • Moles of gas increases • Figure 5.1.8 The effects of increasing the number of moles of gas particles at constant temperature and pressure .
