100 POINTS! Final Honor Activity Question
An unbreakable meteorological balloon is released from the ground. Ground level pressure is 98.5 kPa and the temperature is 18oC. The balloon contains 74.0 dm3 of hydrogen gas. As the balloon ascends, the pressure drops to 7.0 kPa.
What is the new volume of the balloon, assuming no temperature change?

If a temperature drop of 80oC occurs, what is the new volume of the balloon?

Of the two factors, pressure and temperature, which had the greatest effect in changing the volume of the balloon? Support your answer with your calculations.

Approximately 160 km above the Earth the pressure of the atmosphere is about 3.00 x 10-4 Pa and the temperature is about -180oC. If 100 cm of a gas at STP is released at this distance from the Earth, what volume would it occupy?
