    Correct Answer
    A. It is water in a gas state.
    Explanation
    Water vapor is the gaseous state of water. When water evaporates, it turns into water vapor, which is invisible to the naked eye. Water vapor is present in the Earth's atmosphere and plays a crucial role in the water cycle, as it can condense to form clouds and precipitation. Unlike water in a solid or liquid state, water vapor does not have a definite shape or volume. It is measurable and can be quantified using various instruments such as a hygrometer.

    The __________________ catches sound waves and funnels them in toward the eardrum.

    • Hammer

    • Outer ear

    • Cochlea

    • Auditory never

    Correct Answer
    A. Outer ear
    Explanation
    The outer ear catches sound waves and funnels them in toward the eardrum. It consists of the pinna, which acts as a funnel to collect sound waves, and the ear canal, which directs the sound waves towards the eardrum. The outer ear plays a crucial role in capturing and transmitting sound to the middle ear for further processing.

    What type of heat transfer is mainly seen with solids?

    • Convection

    • Conduction

    • Radiation

    • Reflection

    Correct Answer
    A. Conduction
    Explanation
    Conduction is the correct answer because solids are good conductors of heat. In conduction, heat is transferred through direct contact between particles in a solid material. The particles gain energy and vibrate, passing the energy to neighboring particles, thus transferring heat. This process is commonly observed in materials like metal, where heat is easily conducted and dispersed throughout the solid. Convection and radiation, on the other hand, are more commonly associated with fluids and gases.

    This is the gaseous form of water.

    • Precipitation

    • Sleet

    • Snow

    • Water vapor

    Correct Answer
    A. Water vapor
    Explanation
    Water vapor is the correct answer because it is the gaseous form of water. When water evaporates, it turns into water vapor and rises into the atmosphere. Water vapor is invisible to the naked eye, but it can condense into visible clouds or form precipitation such as rain, sleet, or snow. Therefore, water vapor is the correct answer as it represents the gaseous state of water.
