Senior One Quiz No.5 (Nano Part 2 ) - Quiz

Quiz Preview

  • 2. 

    Yo increase the ability of solar cells on converting energy we use......

    • Normal silicon

    • Nano silicon

    • Silver

    • None

    Correct Answer
    A. Nano silicon
    Explanation
    Nano silicon is the correct answer because it refers to the use of silicon at the nanoscale level. By reducing the size of silicon particles to the nanoscale, the surface area increases, allowing for more efficient absorption of sunlight and conversion of energy. This increased surface area also enhances the electrical conductivity of the solar cells, resulting in improved performance and higher energy conversion efficiency compared to normal silicon. Using nano silicon in solar cells can therefore enhance their ability to convert energy from sunlight.

    Some places suffer from the impurities of their drinking water, which of the following can help on solving problems

    • Carbon nano tubes

    • Nano fibres

    • Thin films 

    • None

    Correct Answer
    A. Nano fibres
    Explanation
    Nano fibers can help in solving problems related to impurities in drinking water. Nano fibers have a high surface area to volume ratio, which allows them to effectively filter out contaminants and impurities from water. They can trap particles, bacteria, and other pollutants, ensuring cleaner and safer drinking water. Nano fibers also have a strong mechanical strength and chemical stability, making them durable and effective in water filtration systems. Therefore, the use of nano fibers can be a viable solution to address the impurities in drinking water in certain places.

    The nano filters is ...... Nano materials

    • 1D

    • 2D

    • 3D

    • Nona

    Correct Answer
    A. 1D
    Explanation
    The correct answer is 1D because nano filters are made using one-dimensional nano materials. One-dimensional nano materials refer to materials that have a nanoscale dimension in one direction, such as nanowires or nanotubes. These materials are used to create filters with extremely small pore sizes, allowing them to effectively remove contaminants at the nanoscale level.

  • 5. 

    Which quantity is the least?

    • Mili

    • Micro

    • Nano

    • Nano

    Correct Answer
    A. Nano
    Explanation
    Nano is the least quantity because it is the smallest unit of measurement among the given options. Mili is larger than micro, which is larger than nano. Therefore, nano is the smallest quantity.
