It is released and rises to an altitude of 6.36km, where the pressure is 409mmHg and the temperature is 20.1C. The volume of the balloon at this altitude is L. 2 more group attempts remaining Use the References to access important values if needed for this question. A sample of argon gas occupies a volume of 8.71L at 45.0C and 1.13atm. If it is desired to increase the volume of the gas sample to 10.4L, while decreasing its pressure to 0.858 atm, the temperature of the gas sample at the new volume and pressure must be C. Use the References to access important values if needed for this question. A sample of argon gas occupies a volume of 7.62L at 51.0C and 318 torr. If the volume of the gas sample is decreased to 4.81L, while its temperature is increased to 104.0C, the resulting gas pressure will be torr. 2 more group attempts recaaining
