Part A Calculate the final pressure, in atmospheres, for each of the following, if n and V are constant. A gas with an initial pressure of 1.15 atm at 71 C is cooled to -38 C. P = ? atm Part B A sample of N gas with an initial pressure of 780. mmHg at -75 C is heated to 36 C. ? P = atm Part A A very flexible helium-filled balloon is released from the ground into the air at 20. C. The initial volume of the balloon is 5.00 L, and the pressure is 760. mmHg. The balloon ascends to an altitude of 20 km, where the pressure is 76.0 mmHg and the temperature is -50. C. What is the new volume, V, of the balloon in liters, assuming it doesn't break or leak? Express your answer with the appropriate units. View Available Hint(s) ? V = Value Units Part B Consider 4.60 L of a gas at 365 mmHg and 20. C. If the container is compressed to 2.60 L and the temperature is increased to 34 C, what is the new pressure, P2, inside the container? Assume no change in the amount of gas inside the cylinder. Express your answer with the appropriate units. View Available Hint(s) P = Value ? Units During laparoscopic surgery, carbon dioxide gas is used to expand the abdomen to help create a larger working space. Part A If 5.30 L of CO2 gas at 13 C at 795 mmHg is used, what is the final volume, in liters, of the gas at 37 C and a pressure of 753 mmHg, if the amount of CO2 remains the same? Vco = ? L Part A A gas sample has a volume of 4230 mL at 15 C and 740. mmHg. What is the final temperature, in degrees Celsius, after the sample is transferred to a different container with a volume of 2.45 L and a pressure of 1.50 atm when is constant? Express your answer using two significant figures. T = ? C A sample of helium gas has a volume of 4.70 L at a pressure of 895 mmHg and a temperature of 28 C. Part A What is the pressure of the gas in atm when the volume and temperature of the gas sample are changed to 1690 mL and 340 K if the amount of gas is constant? ? P = atm A sample of helium gas has a volume of 4.70 L at a pressure of 895 mmHg and a temperature of 28 C. Part B What is the pressure of the gas in atm when the volume and temperature of the gas sample are changed to 2.40 L and 13 C if the amount of gas is constant? P2 atm Part A What is the total pressure, in millimeters of mercury, of a gas mixture containing argon gas at 0.33 atm, helium gas at 250 mmHg, and nitrogen gas at 310 torr? Express your answer using two significant figures. Ptotal = ? mmHg The air in a 6.00 L tank has a pressure of 1.90 atm. What is the final pressure, in atmospheres, when the air is placed in tanks that have the following volumes, if there is no change in temperature and amount of gas? ? P = atm Review Constants Periodic la The air in a 6.00 L tank has a pressure of 1.90 atm. What is the final pressure, in atmospheres, when the air is placed in tanks that have the following volumes, if there is no change in temperature and amount of gas? Part B 2600. mL Express your answer using four significant figures. P = ? atm The air in a 6.00 L tank has a pressure of 1.90 atm. What is the final pressure, in atmospheres, when the air is placed in tanks that have the following volumes, if there is no change in temperature and amount of gas? Part C 880. mL Express your answer using three significant figures. P3 = ? atm
