Question

a) A helium-filled weather balloon has a volume of 655 L at14.9°C and 757mmHg. It is released and rises to an altitude of 4.01 km, where the pressure is 538 mmHg and the temperature is–8.1°C. The volume of the balloon at this altitude is L.

b) A sample of heliumgas occupies a volume of 9.33 L at 42.0°C and 0.870 atm.If it is desired to increase the volume of the gas sample to 11.4 L, while increasing its pressure to 1.16 atm, the temperature of the gas sample at the new volume and pressure must be °C.

c) A sample of kryptongas occupies a volume of 6.93 L at 62.0°C and 399 torr.If the volume of the gas sample isincreased to 8.48 L, while its temperature is decreased to –11.0°C, the resulting gas pressure will be torr.
