Name: ________________________ Class: ___________________ Date: __________ ID: A1AP Chapter 10 Study QuestionsTrue/FalseIndicate whether the statement is true or false.1. The main component of air is oxygen.2. If the temperature is lowered from 60°C to 30°C, the volume of a fixed amount of gas will be one half the original volume.3. A gas is considered "ideal" if one mole of it in a one-liter container exerts a pressure of exactly 1 atm at room temperature.4. Kinetic-molecular theory assumes that attractive and repulsive forces between gas particles are stronger than those between gas particles and container walls.5. According to the kinetic-molecular theory, molecules of different gases at the same temperature always have the same average kinetic energy.6. The effusion rate of a gas is proportional to the square root of its molar mass.7. Two deviations of real gases from ideal gases which are treated in the van der Waals equation are finite molecular volume and non-zero molecular attractions.Multiple ChoiceIdentify the choice that best completes the statement or answers the question.8. A gas at a pressure of 10.0 Pa exerts a force of __________ N on an area of 5.5 m2.a.55 b. 0.55 c.5.5 d.1.8 e.189. A gas at a pressure of 325 torr exerts a force of __________ N on an area of 5.5 m2.10. A pressure of 1.00 atm is the same as a pressure of __________ of mm Hg.33.011. The National Weather Service routinely supplies atmospheric pressure data to help pilots set their altimeters. The units the NWS uses for atmospheric pressure are inches of mercury. barometric pressure of 30.51 inches of mercury corresponds to __________ kPa.A 12. A closed-end manometer was attached to a vessel containing argon. The difference in the mercury levels in the two arms of the manometer was 12.2 cm. Atmospheric pressure was 783 mm Hg. The pressure of the argon in the container was __________ mm Hg.a.122 b. 661 c.771 d.795 e.88213. A sample of gas (24.2 g) initially at 4.00 atm was compressed from 8.00 L to 2.00 L at constant temperature. After the compression, the gas pressure was __________ atm.16.014. A sample of a gas (5.0 mol) at 1.0 atm is expanded at constant temperature from 10 L to 15 L. The final pressure is __________ atm.15

Name: ________________________ ID: A215. A balloon originally had a volume of 4.39 L at 44 °C and a pressure of 729 torr. The balloon must be cooled to __________°C to reduce its volume to 3.78 L (at constant pressure).546
