1) If we want to expand a gas to double its original volumewithout changing the pressure, we will need to _______ the absolute temperature
2)A sample of O2 gas with a volume of 9.31 L was collected at 137 °C. What is the volume of the gas if the temperature is changed to 16 °C at constant pressure?
3)The initial volume of a sample of argon gas is 552 mL at-97°C. If the pressure is held constant and the volume is changed to 933 mL, what will be the new temperature (in°C)?
