answer both question write neatly

A helium-filled weather balloon has a volume of 897 L at 22.9C and 756 mmHg. It is released and rises to an altitude of 3.60 km, where the pressure is 559 mmHg and the temperature is - 1.1C. The volume of the balloon at A sample of oxygen gas occupies a volume of 9.49 L at 56.0C and 409 torr. If the volume of the gas sample is decreased to 7.19 L, while its temperature is decreased to -6.0C, the resulting gas pressure will be A sample of oxygen gas at 309 K and 0.247 atm occupies a volume of 3.13 L. If the pressure of the gas is decreased, while at the same time it is heated to a higher temperature, the final gas volume O could be larger or smaller than 3.13 L depending on the final pressure and temperature. O will be smaller than 3.13 L. O will be larger than 3.13 L
