Questions and Answers
  • 1. 

    How many states of matter are there?

    • A.

      5

    • B.

      2

    • C.

      3

    • D.

      4

    Correct Answer
    A. 5
    Explanation
    Matter encompasses entities that occupy space and possess mass, such as air, water, and notebooks. Traditionally, matters manifest in three states under normal conditions, but scientific exploration has unveiled two additional states. These states undergo transitions facilitated by the absorption or release of heat energy. The five distinct states of matter include Bose-Einstein condensate, solid, liquid, gas, and plasma.

    Rate this question:

  • 2. 

    The conversion of matter from solid state to liquid state is called

    • A.

      Vaporization.

    • B.

      Melting

    • C.

      Evaporation

    • D.

      Condensation

    Correct Answer
    B. Melting
    Explanation
    Melting is the correct answer because it refers to the process by which a substance changes from its solid state to its liquid state. This occurs when heat is applied to a solid, causing its particles to gain enough energy to break free from their fixed positions and move more freely, resulting in the substance becoming a liquid.

    Rate this question:

  • 3. 

    Which of the following does not take the shape of the container it is in?

    • A.

      A pencil.

    • B.

      Oil

    • C.

      Water.

    • D.

      Air

    Correct Answer
    A. A pencil.
    Explanation
     A pencil does not take the shape of the container it is in because it is a solid object with a fixed shape. Unlike liquids such as oil and water and gasses like air, solids have a fixed shape regardless of the container they are placed in.

    Rate this question:

  • 4. 

    I can easily compress the water in a jar to reduce its volume.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    Water is an incompressible substance, meaning that its volume cannot be easily reduced by applying pressure. Unlike gasses, which can be compressed, water molecules are tightly packed together and have very little empty space between them. Therefore, it is not possible to compress water in a jar to reduce its volume easily.

    Rate this question:

  • 5. 

    When water evaporates, it turns into solid.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    Water does not turn into a solid when it evaporates. Evaporation is the process by which water changes from a liquid state to a gas state. When water evaporates, it turns into water vapor, not a solid.

    Rate this question:

  • 6. 

    Which state of matter spreads itself thinner and thinner until it fills the entire volume of the container irrespective of its size?

    • A.

      Liquid

    • B.

      Gas

    • C.

      Solid

    • D.

      All of the above

    Correct Answer
    B. Gas
    Explanation
    Gas has the ability to spread itself thinner and thinner and fill the entire volume of the container. In the gas state, the particles are highly energetic and move freely, causing them to spread out and fill the available space. 

    Rate this question:

  • 7. 

    Water conforms in all directions to take the shape of the container it is in.

    • A.

      False.

    • B.

      True

    Correct Answer
    B. True
    Explanation
    Water is a liquid, and liquid particles can slide against each other easily. This allows water and other liquid particles to take the shape of their containers. 

    Rate this question:

  • 8. 

    Select the correct statement:

    • A.

      An ice cube becomes gas at its melting point.

    • B.

      An ice cube becomes liquid at its melting point.

    • C.

      Both of the above

    • D.

      None of the above

    Correct Answer
    B. An ice cube becomes liquid at its melting point.
    Explanation
    At its melting point, an ice cube undergoes a phase change from a solid to a liquid. This is because the melting point is the temperature at which the solid ice gains enough energy to break its rigid structure and transition into a more fluid state. Therefore, the correct statement is that an ice cube becomes liquid at its melting point.

    Rate this question:

  • 9. 

    Choose the right statement. In solids, the molecules are packed the closest together. In gasses, the molecules are spread out the most. In liquids, the molecules are packed closer together.

    • A.

      Statement a alone is right.

    • B.

      Statement b alone is right

    • C.

      All the above statements are right.

    • D.

      None of the above is right.

    Correct Answer
    C. All the above statements are right.
    Explanation
    The correct answer is "All the above statements are right." This is because the statements in options a, b, and c are all individually correct. In solids, the molecules are packed the closest together, in gasses, the molecules are spread out the most, and in liquids, the molecules are packed closer together. Therefore, all three statements are true, making option d incorrect.

    Rate this question:

  • 10. 

    Pick the true statement/s:

    • A.

      Liquids can freeze.

    • B.

      Gases can freeze.

    • C.

      Solids can freeze.

    • D.

      All are correct.

    Correct Answer
    A. Liquids can freeze.
    Explanation
    The statement "Liquids can freeze" is correct because liquids can undergo a phase change and solidify when their temperature is lowered below their freezing point. This process is commonly observed in everyday life when water turns into ice. On the other hand, gasses cannot freeze directly into a solid state; they first need to undergo condensation to become a liquid before freezing. Solids, by definition, are already in a frozen state and do not freeze further. Therefore, the correct statement is that liquids can freeze.
