1/ A weather balloon is inflated to a volume of 29.8 L at a pressure of 753 mmHg and a temperature of 25.3 âC. The balloon rises in the atmosphere to an altitude where the pressure is 370. mmHg and the temperature is -15.4 âC.
Assuming the balloon can freely expand, calculate the volume of the balloon at this altitude.
Vballon=
2/ syringe containing 1.68 mL of oxygen gas is cooled from 99.1 âC to 0.4 âC. What is the final volume Vf of oxygen gas? (Assume that the pressure is constant.)
