Physics Quiz: Gas Laws and p1V1 = p2V2

Instructions:

Please answer the following questions related to the ideal gas law and the equation ( p_1V_1 = p_2V_2 ). Write your answers in the space provided. Each question has only one correct answer.


  1. What does ( p_1 ) represent in the equation ( p_1V_1 = p_2V_2 )?
    Answer:

  2. In the context of the equation, what does ( V_1 ) refer to?
    Answer:

  3. If the pressure of a gas doubles, how does it affect the volume if the temperature and amount of gas remain constant? Explain using the equation ( p_1V_1 = p_2V_2 ).
    Answer:

  4. Consider a gas with an initial volume of 2.0 L and an initial pressure of 1.0 atm. If the volume changes to 4.0 L, what will be the new pressure ( p_2 )?
    Answer:

  5. What happens to the volume of a gas if the pressure is halved, assuming that the temperature remains constant? Use the relationship in ( p_1V_1 = p_2V_2 ) to explain.
    Answer:

  6. If you have a gas at a pressure of 3.0 atm and a volume of 1.5 L, what will the product ( pV ) be before changing conditions?
    Answer:

  7. If a gas is compressed to half its volume, how would you mathematically express this change using the equation ( p_1V_1 = p_2V_2 )?
    Answer:

  8. When temperature is held constant, what type of relationship exists between pressure and volume according to Boyle’s Law?
    Answer:

  9. How would you define the term 'ideal gas' and how does it relate to the equation ( p_1V_1 = p_2V_2 )?
    Answer:

  10. Describe a real-world scenario where the relationship ( p_1V_1 = p_2V_2 ) would apply, and explain why it's significant.
    Answer:

  11. What is the significance of the variables ( p_2 ) and ( V_2 ) in situations where gas volume is altered?
    Answer:

  12. Using the concept of the ideal gas law, explain how increasing the temperature of a gas at constant pressure would affect its volume.
    Answer:

  13. If you have a balloon filled with air at 1.0 atm pressure and a volume of 30.0 L, and it is then brought to a height where the atmospheric pressure is 0.5 atm, what will be the new volume of the balloon?
    Answer:

  14. What units are commonly used for pressure when applying the equation ( p_1V_1 = p_2V_2 ) in SI units?
    Answer:

  15. In terms of ideal gas behaviour, why is the relationship ( p_1V_1 = p_2V_2 ) important in understanding gas properties and changes?
