Question
1. A sample of oxygen gas occupies a volume of 436.2 mL at 1.02 atm. If the
temperature is held constant,
(a) What would the pressure of this gas be when the gas is compressed to 231.6
mL?
(b) State the gas law which applies.
2. If a gas originally occupying 6.75 L at 19.21 °C and 762.5 torr is compressed to
give a pressure of 1.26 atm at 26.35 °C,
(a) What would the new volume be?
(b) State the gas law which applies.
3. A balloon containing 5.0 dm3 of gas at 14 °C and 100.0 kPa rises to an altitude of
2000 m, where the temperature is 20 °C. The pressure of the gas in the balloon
is now 79.0 kPa. What is the volume of gas in the balloon at this altitude?
