Which of these is the best hypothesis for why your tire's air pressure is low? If the pressure in the tire is low, then the tire lost air pressure because air is escaping through a hole in the tire. If the pressure in the tire is low, then someone let air out of the tire, because tires do not lose air naturally.

Before it was launched, a helium-filled balloon had a pressure of 201 kpa at a temperature of 27°c. at an altitude of 15,000 m, the pressure had decreased to 2.5 kpa and the temperature had dropped to -14 °c. the volume of the balloon increased to 59.3 m3. what is the original volume of the balloon? 13 m3 0.85 m3 0.077 m3 1.17 m3
