Question
The diagrams below show four open-ended manometers at room temperature and standard atmospheric pressure. For each of the questions that follow, write the letter of the diagram that best answers the question. Each letter can be used once, more than once, or not at al. GAS GAS GAS 13. In which manometer is the gas pressure the greatest? 14. Which manometer contains a gas at a pressure of 90 kPa? 15. Which manometer could have a leak? 16. In which manometer is the gas pressure the lowest? Solve each of the following problems as directed 17, 738 mm Hg. atm 18. 987 kh:- atm 19. 32.0 lb/sq in. atm 20. 380 torr 21. 200,000 pascals= atm 22. 0.88 bar-atm 23. An open-ended manometer is carried up in a hot-air balloon from sea-level to an altitude of atm 5 km. Calculate the air pressure, in atm, at this new altitude if the mercury level has risen 35 mm higher in the open-end side of the tube. Show all your calculations. (Discount any changes in temperature) 13-3 Review and Reinforcement The Gas Laws Match each chemist to one of the gas laws below 1. The pressure of a gas is inversely proportional Avogadro b. Charles a. to its volume. 2. The sum of the partial pressures of gases in a of gases in a c Boyle Boyle c. d. Dalton mixture is equai to the total pressure of mixture. Equal volumes of gases contain equal numbers of particles The volume of a gas is directly proportional to its temperature. -3, 4- _Explanation / Answer
