Unformatted text preview: highway. Along the way, the temperature of the tire reaches 140 o F (60. o C). What is the pressure in the tires? Another Boyles Law Example An inflated balloon has a volume of 0.55 L at sea level. It is allowed to rise to a height of 6.5 km, where the pressure is about 0.40 atm. Assuming the temperature remains constant, what is the final volume of the balloon? Another Charles Law Example A 452-mL sample of fluorine gas is heated from 22 o C to 187 o C at constant pressure. What is the final volume of the gas?...
