A helium-filled weather balloon has a volume of 731 L at 23.9°C and 754 mmHg. It is released and rises to an altitude of 2.07 km, where the pressure is 641 mmHg and the temperature is 9.9°C. The volume of the balloon at this altitude is L.A sample of nitrogen gas occupies a volume of 6.89 L at 60.0°C and 354 torr.If the volume of the gas sample is decreased to 5.85 L, while its temperature is increased to 134.0°C, the resulting gas pressure will be torr.

1) Using state equation, P1V1/T1 = P2V2/T2 754×731/296.9 = 641×V2/282.9 V2 =819L

Answered: volume of the balloon at this altitude…

Question

A helium-filled weather balloon has a volume of 731 L at 23.9°C and 754 mmHg. It is released and rises to an altitude of 2.07 km, where the pressure is 641 mmHg and the temperature is 9.9°C. The volume of the balloon at this altitude is L.
A sample of nitrogen gas occupies a volume of 6.89 L at 60.0°C and 354 torr.

If the volume of the gas sample is decreased to 5.85 L, while its temperature is increased to 134.0°C, the resulting gas pressure will be torr.
