    V1/T1 = V2/T2 Charles' law

    Rate this question:

  • 8. 

    If the air inside a balloon is heated, the volume will:

    • A.

      Increase

    • B.

      Decrease

    • C.

      Increase a little, then decrease.

    Correct Answer
    A. Increase
    Explanation
    Temperature and Volume are directly related (Charles' law): When temperature is increased, volume will also increase.

    Rate this question:

  • 9. 

    According to the Kinetic Theory of Gases which is true.

    • A.

      Gases are compressible because of the space between particles.

    • B.

      The distance between molecules in ideal gases is closer than in liquids or solids.

    • C.

      The gases are NOT fluid

    Correct Answer
    A. Gases are compressible because of the space between particles.
    Explanation
    According to the Kinetic Theory of Gases, gases are compressible because of the space between particles. This is because gas particles are in constant random motion and have a lot of empty space between them. When pressure is applied to a gas, the particles can be pushed closer together, reducing the volume of the gas. In contrast, in liquids and solids, the particles are much closer together and have less empty space between them, making them less compressible. Therefore, the statement that gases are compressible because of the space between particles is true based on the Kinetic Theory of Gases.

    Which of the following describes the relationship between P and V?

    • A.

      Directly proportional

    • B.

      Inversely proportional

    • C.

      Unrelated

    Correct Answer
    B. Inversely proportional
    Explanation
    The relationship between P and V is inversely proportional. This means that as one variable increases, the other variable decreases, and vice versa. In other words, when P increases, V decreases, and when P decreases, V increases. There is a consistent and predictable relationship between the two variables, where they vary in opposite directions. This can be represented by the equation P = k/V, where k is a constant.

    Boyle's Law expresses the relationship between

    Correct Answer
    pressure and volume, p and v, volume and pressure, v and p
    Explanation
    Boyle's Law states that there is an inverse relationship between the pressure and volume of a gas at constant temperature. This means that as the pressure increases, the volume decreases, and vice versa. The variables p and v represent pressure and volume respectively, and the answer correctly states that Boyle's Law expresses the relationship between these two variables. The second part of the answer simply repeats the same information in a different order, stating that Boyle's Law also relates volume and pressure, represented by the variables v and p.

    Rate this question:

  • 12. 

    T1/P1 = T2/P2 is Charles's Law

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    The given statement, T1/P1 = T2/P2, is not Charles's Law. Charles's Law states that the volume of a gas is directly proportional to its temperature, assuming constant pressure. The correct equation for Charles's Law is V1/T1 = V2/T2. Therefore, the answer is false.
