  • Q2
    Which of the following expressions correctly represents Charles\' Law?
    V_1T_1 = V_2T_2
    PV = nRT
    P_1V_1 = P_2V_2

  • Q4
    How does Charles\' Law apply to the behavior of a hot air balloon?
    Heating the air inside the balloon increases its volume, making the balloon rise.
    Cooling the air inside the balloon decreases its volume, making the balloon rise.
    The pressure inside the balloon increases without changing volume.
    The volume of the balloon remains constant regardless of temperature.

    2.5 L
    3.0 L
    4.0 L
    1.5 L

  • Q6
    If the temperature of a gas is doubled at constant pressure, what happens to its volume according to Charles Law?
    The volume halves.
    The volume remains the same.
    The volume also doubles.
    The volume decreases by a quarter.

  • Q7
    According to Charles Law, if a gas is cooled down while its pressure is held constant, what happens to its molecules?
    The molecules become electrically charged.
    The molecules move slower and come closer together.
    The molecules move faster and spread apart.
    The molecules do not change their speed.
