1. The inflated balloon that slipped from the hand of Renn has a volume of 0.50 L at sea level (1.0 atm) and it reached a height of approximately 8 km where the atmospheric pressure is approximately 0.33 atm. Assuming that the temperature is constant, compute for the final volume of the balloon. 2. Oxygen gas inside a 1.5 L-gas tank has a pressure of 0.95 atm. Provided that the temperature remains constant, how much pressure is needed to reduce its volume by ? 3. 1. A gas occupies 900.0 mL at a temperature of 27.0 °C. What is the volume at 132.0°C? 4. A tire is filled to a gauge pressure of 2 atm at 27°C. After a drive, the temperature within the tire rises to 47°C. What is the pressure within the tire now? 5. 1. The initial temperature of a 1.00 liter sample of argon is 20°C. The pressure is decreased from 720 mm Hg to 360 mm Hg and the volume increases to 2.14 liters. What was the change in temperature of the argon in Celsius? 6. A 7.25 L sample of nitrogen gas (N2) is identified to contain 0.75 mole of nitrogen. How many moles of nitrogen gas would there be in a 20.0 L sample provided the temperature and pressure remains the same? 7. At what temperature will 0.654 moles of neon gas occupy 12.30 liters at 1.95 atmospheres?​
