1. A sample of gas under a pressure of 622 kPa has a volume of 233 mL. Thepressure is increased to 988 kPa, while the temperature remains constant.What volume will the gas occupy at this pressure? 2. The pressure exerted by a gas is 2.0 atm while it has a volume of 350 mL .What would be the volume of this sample of gas at standard atmospheric pressure? 3. A sample of CO2 has a volume of 2.7 L at 239 kPa. What would the new pressure be if the volume was increases to 4.5 L? Charles's Law 4. What volume will a sample of hydrogen occupy at 28.0 oC if the gas occupies a volume of 2.23 mL at a temperature of 0.0 oC? Assume that the pressure remains constant. (remember to change to Kelvin). 5. If a gas occupies 733 mL at 10.0 oC, at what temperature will it occupy 950 mL? Assume that pressure remains constant. 6. A gas occupies 560 mL at 285 K. To what temperature must the gas be lowered to, if it is to occupy 25.0 mL? Assume a constant pressure.
