A sample of hydrogen gas occupies a volume of 6.68 L at 57.0°C and 1.12 atm. If it is desired to decrease the volume of the gas sample to 5.07 L, while increasing its pressure to 1.45 atm, the temperature of the gas sample at the new volume and pressure must be pc.
A sample of nitrogen gas occupies a volume of 7.87 L at 56.0°C and 340. torr. If the volume of the gas sample is decreased to 5.71 L, while its temperature is increased to 129.0°C, the resulting gas pressure will be torr.
A 6.42 L sample of gas has a pressure of 1.51 atm and a temperature of 85°C. The sample is allowed to expand to a volume of 8.09 L and is cooled to 30 °C. Calculate the new pressure of the gas, assuming that no gas escaped during the experiment. atm
