SUMMARY
The volume ratio of a helium balloon at an altitude of 3330 m compared to sea level is calculated using the Ideal Gas Law, represented by the equation PV/T = PV/T. At sea level (20.0°C, 1 atm), the balloon's volume is compared to its volume at 3330 m (5.0°C, 0.65 atm). The final calculated volume ratio is 0.94, indicating a decrease in volume due to lower pressure and temperature at higher altitudes. The tension in the rubber also contributes to the internal pressure of the balloon.
PREREQUISITES
- Understanding of the Ideal Gas Law (PV=nRT)
