Read each question carefully and answer to the best of your ability. Show all your work for calculation problems.
1. Which of the following is NOT a primary variable used to describe the state of a gas?
Pressure
Volume
Density
Temperature
2. According to Boyle's Law, if the temperature and number of moles of a gas are kept constant, what happens to the volume as pressure increases?
Volume increases
Volume decreases
Volume remains constant
Volume fluctuates
3. The SI unit for pressure is the .
4. Charles's Law states that for a fixed amount of gas at constant pressure, the volume is directly proportional to its temperature.
5. Avogadro's Law states that equal volumes of all gases, at the same temperature and pressure, have the same number of .
6. Explain the relationship between temperature and the kinetic energy of gas particles.
7. Describe a real-world application of one of the gas laws.
8. Increasing the number of gas particles in a fixed volume will decrease the pressure.
True
False
9. The Ideal Gas Law combines Boyle's, Charles's, and Avogadro's Laws.
True
False
10. A gas occupies a volume of 2.5 L at a pressure of 1.0 atm. If the pressure is increased to 3.0 atm while keeping the temperature constant, what will be the new volume of the gas? (Hint: Use Boyle's Law)
11. A 5.0 L container of gas is at 27°C. If the temperature is increased to 127°C while keeping the pressure constant, what is the new volume of the gas? (Hint: Use Charles's Law and remember to convert temperatures to Kelvin).
