- An arctic weather balloon is filled with 1.56L of helium gas inside a prep shed. The temperature inside the shed is 11.°C. The balloon is then taken outside, where the temperature is 2.°C. Calculate the new volume of the balloon.You may assume the pressure on the balloon stays constant at exactly 1atm. Round your answer to 3 significant digits.The tires on a race car are filled with air at 10o C, to a gauge pressure of 35 lb/in2 (about 2.4 x 105 Pa). The gauge pressure is the difference between the pressure in the tire and the atmospheric pressure outside the tire. During the race, the tires heat up to 120o C. What will be the gauge reading for the tire pressure at this temperature?If a pneumatic cylinder has a volume of 14 cu. in. at 1000 PSIG (1000 Pounds per square inch gauge) when the temperature is 85°F and then the temperature is elefated to 125°F by compression to 12 cu. in.
