    Rate this question:

  • 18. 

    The amount of heat which is absorbed or evolved in changing the state of a substance without changing its temperature.

    • A.

      Mechanical Heat

    • B.

      Latent Heat

    • C.

      Solar Heat

    • D.

      Convertible Heat

    Correct Answer
    B. Latent Heat
    Explanation
    Latent heat refers to the amount of heat absorbed or evolved when a substance undergoes a change in state without a change in temperature. This means that during processes like melting, boiling, or condensation, the substance either absorbs or releases energy, resulting in a change of state. The term "latent" refers to the hidden or concealed nature of this heat exchange, as it does not directly affect the temperature of the substance. Therefore, latent heat is the most appropriate term to describe this phenomenon.

    • C.

      Thread

    • D.

      Rise Detector

    Correct Answer
    A. Fascia Plate
    Explanation
    The fascia plate is the correct answer because it serves as a safety feature that prevents passengers from falling into the hoistway when they try to exit the elevator car. It acts as a barrier between the car and the hoistway, ensuring that passengers cannot accidentally step into the open shaft when the elevator is stopped between floors.

    Rate this question:

  • 23. 

    The bending of sound wave when traveling forward changes direction as it passes through different densities. 

    • A.

      Diffusion

    • B.

      Reflection

    • C.

      Refraction

    • D.

      Deflection

    Correct Answer
    C. Refraction
    Explanation
    When a sound wave travels through different densities, such as from air to water or vice versa, its path is bent or changed in direction. This phenomenon is known as refraction. Refraction occurs because the speed of sound changes as it travels through different mediums, causing the wave to bend towards or away from the normal line. This change in direction is responsible for various auditory experiences, such as the bending of sound around obstacles or the focusing of sound waves in certain areas.

    • C.

      Cycle

    • D.

      Loop

    Correct Answer
    A. Frequency
    Explanation
    Frequency refers to the number of cycles or oscillations that occur in a unit of time. It is typically measured in hertz, which represents the number of cycles per second. In other words, frequency tells us how many times a wave or oscillation repeats itself in a given time period. Therefore, the correct answer is Frequency.

      Chandelier

    • C.

      Torchiere

    • D.

      Sconce

    Correct Answer
    C. Torchiere
    Explanation
    A torchiere is a floor lamp that has its light source within a reflecting bowl that directs the light upward. This design allows for the light to be emitted in an upward direction, creating a soft and indirect illumination in the room. The reflecting bowl helps to enhance the light output and distribute it evenly in the space. The other options - gooseneck lamp, chandelier, and sconce - do not have this specific feature of a reflecting bowl directing the light upward, making torchiere the correct answer.

    Explanation
    A dead air space refers to an unventilated area where the air does not circulate. This term is commonly used in relation to insulation or building design, where an unventilated space can lead to poor air quality and temperature regulation. The term "dead" implies that the air in this space is stagnant and does not move, which can have negative effects on the overall environment. The other options, loose space, airway, and void, do not accurately describe the specific characteristic of the air in an unventilated space.
