You have a balloon filled with 5 mL of air at a pressure of 5 atm. You pop the balloon, changing the pressure of the air to 1.0 atm.
What will the new volume be? And how will the volume change increase or decrease

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
