Multiple-choice questions may continue on the next column or page – find all choices before answering. 00110.0 pointsA gas has a volume of 2.0 L at a pressure of3.00 atm. What pressure is needed to changethe volume to 6.00 L at constant temperature? 1.2.0 atm2.1.0 atmcorrect3.9.0 atm4.4.0 atmExplanation:V1= 2.00 LP1= 3 atmV2= 6.00 LBoyle’s law,P1V1=P2V2, relates the vol-ume and pressure of a sample of gas.P2=P1V1V2=(3.00 atm) (2.00 L)6.00 L= 1.0 atm00210.0 pointsAt constant temperature if the volume of agas sample is tripled the pressure will 3V1=V2Boyle’s Law relates the volume and pressureof a sample of gas: P 1 = 3 P 2 P 2 = 1 3 P 1 003 10.0 points A certain quantity of a gas occupies 61.3 mLat 68C. If the pressure remains constant,what would be the volume of the gas at128C? 10.0 points If a sample of gas is heated from 100C to300C at constant pressure, the volume will?by a factor of?.
padilla (tp5647) – Homework 9 – Sutcliffe – (53770) 2 T 2 = 300 C + 273 = 573 K The temperature increases by a factor of 573 373 = 1 . 5. According to Charles’ Law, the volume of the gas would increase by the same factor. 005 10.0 points A sample of a gas occupies 460 mL at 70.0 C and 1.00 atmosphere. At what temperature would the gas occupy 650 mL at the same pressure? 4Pa. What is the volumeof air at STP that an individual breathes inone day? Give your answers in cubic meters. 1. 9 . 98 m 3 / day correct 2. 505 cm 3 / day 3. 505 m 3 / day 4. None of these 5. 100 m 3 / day 6. 9 . 95 cm 3 / day Explanation:
