A sample of nitrogen gas occupies a volume of 8.81 L at 56.0°C and 0.550atm.If it is desired to decrease the volume of the gas sample to 7.74 L, whileincreasing its pressure to 0.674 atm, the temperature of the gas sample at thenew volume and pressure must be ||°C. A helium-filled weather balloon has a volume of 867 L at 14.9°C and 756mmHg. It is released and rises to an altitude of 6.20 km, where the pressure is417 mmHg and the temperature is -21.1°C.The volume of the balloon at this altitude isL.

A large balloon contains 65.0 L of helium gas at 25 C and a pressure of 745 mm Hg. The balloon ascends to 3000 m, at which the external pressure has decreased by 30.%. What would be the volume of the balloon, assuming it expands so that the internal and external pressures are equal? (Assume the temperature is still 25 C.)
A certain flexible weather balloon contains helium gas at a volume of 855 L. Initially, the balloon is at sea level where the temperature is 25C and the barometric pressure is 730 torr. The balloon then rises to an altitude of 6000 ft, where the pressure is 605 torr and the temperature is 15C. What is the change in volume of the balloon as it ascends from sea level to 6000 ft?
Two identical He-filled balloons, each with a volume of 20 L, are allowed to rise into the atmosphere. One rises to an altitude of 3000 m while the other rises to 6000 m. a Assuming that the balloons are at the same temperature, which balloon has the greater volume? b What information would you need in order to calculate the volume of each of the balloons at their respective heights?
Workers at a research station in the Antarctic collected a sample of air to test for airborne pollutants. They collected the sample in a 1.00-L container at 764 torr and 20 C. Calculate the pressure in the container when it was opened for analysis in a particulate-free clean room in a laboratory in South Carolina, at a temperature of 22 C.
