Directions: Work the following problems based on Chapter 14 Section 2. Title: Daily Work 14-2

Match each description in column B to the correct term in column A.

Column A / Column B
_____ 1. Boyle’s Law /
  1. The volume of a fixed mass of gas is directly proportional to its Kelvin temperature if the pressure is kept constant.

_____ 2. Combined gas law /
_____ 3. Absolute zero /
  1. For a fixed mass of gas at constant temperature, the volume of a gas varies inversely with pressure.

_____ 4. Charles’s law /
  1. The pressure of a gas is directly proportional to the Kelvin temperature if the volume remains constant.

_____ 5. Gay-Lussac’s law /
  1. -273.15°C

  1. How are the pressure and volume of a gas related at a constant temperature?
  1. If pressure is constant, how does a change in temperature affect the volume of a gas?
  1. What is the relationship between the temperature and pressure of a contained gas at constant volume?
  1. In what situations is the combined gas law useful?
  1. A gas with a volume of 4.00L at a pressure of 205kPa is allowed to expand to a volume of 12.0L. What is the pressure in the container if the temperature remains constant?
  1. Exactly 5.00L of air at -50.0°C is warmed to 100.0°C. What is the new volume if the pressure remains constant?
  1. The pressure in a car tire is 198kPa at 27°C. After a long drive, the pressure is 225kPa. What is the temperature of the air in the tire? Assume that the volume is constant.
  1. A 5.00L air sample has a pressure of 107kPa at a temperature of -50.0°C. If the temperature is raised to 102°C and the volume expands to 7.00L, what will the new pressure be?
  1. The volume of a weather balloon increases as the balloon rises in the atmosphere. Why doesn’t the drop in temperature at higher altitudes cause the volume to decrease?
