본문 chapter 5 gases 5.13 5.14 Strategy: Because 1 atm 760 mmHg, the following conversion factor is needed to obtain the pressure in atmospheres. For the second conversion, 1 atm 101.325 kPa. Solution: 5.17 (a) If the final temperature of the sample is above the boiling point, it would still be in the gas phase. The diagram that best represents this is choice (d). (b) If the final temperature of the sample is below its boiling point, it will condense to a liquid. The liquid will have a vapor pressure, so some of the sample will remain in the gas phase. The diagram that best represents this is choice (b). 5.18 (1) Recall that . As the pressure is tripled, the volume will decrease to of its original volume, assuming constant n and T. The correct choice is (b). (2) Recall that V ( T. As the temperature is doubled, the volume will also double, assuming constant n and P. The correct choice is (a). The depth of color indicates the density of the gas. As the volume increases at constant moles of gas, the density of the gas will decrease. This decrease in gas density is indicated by the lighter shading. (3) Recall that V ( n. Starting with n moles of gas, adding another n moles of gas (2n total) will double the volume. The correct choice is (c). The density of the gas will remain the same as moles are doubled and volume is doubled. (4) Recall that V ( T and . Halving the temperature would decrease the volume to its original volume. However, reducing the pressure to its original value would increase the volume by a factor of 4. Combining the two changes, we have The volume will double. The correct choice is (a). 5.19 P1 0.970 atm P2 0.541 atm V1 725 mL V2 ?
