    What is the chemical formula for water?

    • H2O 

    • CO2 

    • NaCl 

    • CH4

    Correct Answer
    A. H2O 
    Explanation
    Water's chemical formula, H2O, elucidates its elemental composition: two hydrogen atoms covalently bonded to one oxygen atom. Water is integral to numerous biochemical processes and is vital for sustaining life on Earth. Its unique properties, including polarity, high heat capacity, and universal solvent capabilities, underpin its myriad roles in biological systems, climate regulation, and geological processes.

    What is the process by which plants convert light energy into chemical energy?

    • Photosynthesis 

    • Respiration 

    • Fermentation 

    • Combustion

    Correct Answer
    A. Photosynthesis 
    Explanation
    Photosynthesis is a vital biological process responsible for oxygen production and energy conversion in plants and certain microorganisms. Chlorophyll, located in chloroplasts, absorbs light energy, initiating a series of biochemical reactions. Carbon dioxide and water molecules are converted into glucose and oxygen through a complex process involving light-dependent and light-independent reactions. This process sustains terrestrial life by providing energy-rich organic compounds and oxygen to ecosystems.

    What is the chemical symbol for gold?

    • Au 

    • Ag 

    • Pt 

    • Fe

    Correct Answer
    A. Au 
    Explanation
    The chemical symbol Au derives from the Latin word "aurum," signifying gold's historical significance. This precious metal, valued for its rarity and luster, has been revered throughout human history. It is prized for its malleability, conductivity, and resistance to corrosion, making it indispensable in jewelry, electronics, and currency. Despite its chemical stability, gold can form compounds under specific conditions, albeit less readily than other metals.

    Which of the following is NOT a type of chemical bond? 

    • Ionic bond

    • Covalent bond 

    • Metallic bond 

    • Gravitational bond

    Correct Answer
    A. Gravitational bond
    Explanation
    Chemical bonds are fundamental to the structure and behavior of molecules and compounds. Ionic bonds occur when one atom transfers electrons to another, resulting in the formation of positively and negatively charged ions that attract each other. Covalent bonds involve the sharing of electron pairs between atoms, creating strong bonds. Metallic bonds occur in metals where electrons are delocalized, allowing for conductivity. Gravitational bonds, however, pertain to gravitational forces between masses, not chemical bonding.

    What is the biggest planet?

    • Jupiter

    • Venus

    • Earth

    • Saturn

    Correct Answer
    A. Jupiter
    Explanation
    Jupiter is the correct answer because it is the largest planet in our solar system. It is more than 11 times the diameter of Earth and has a mass more than 300 times that of Earth. Jupiter's size is due to its high concentration of gases, mainly hydrogen and helium, making it a gas giant. Its immense size and strong gravitational pull have allowed it to capture numerous moons, including the four largest known as the Galilean moons. Overall, Jupiter's size sets it apart from the other planets listed as options.

    What is the SI unit of force? 

    • Newton 

    • Watt 

    • Joule 

    • Pascal

    Correct Answer
    A. Newton 
    Explanation
    The newton (N) serves as the standard unit of force in the International System of Units (SI). Named after Sir Isaac Newton, this unit quantifies the amount of force required to accelerate a one-kilogram mass by one meter per second squared. Force, a vector quantity, influences an object's motion and interactions in the physical world, encompassing phenomena such as gravitational attraction, friction, and mechanical work.

  • 8. 

    Which of the following elements is a noble gas? 

    • Hydrogen 

    • Oxygen 

    • Neon 

    • Sodium

    Correct Answer
    A. Neon 
    Explanation
    Noble gases, found in group 18 of the periodic table, possess a stable configuration of electrons in their outer shell. Neon, an inert noble gas, remains unreactive under normal conditions due to its full valence electron shell. This stability makes noble gases valuable in various applications, such as lighting and cryogenics. Hydrogen, oxygen, and sodium are reactive elements, participating in chemical reactions to achieve a stable electron configuration.

    What is the size of the sun?

    • 1.4 million kilometers

    • 3.1 million kilometers

    • 2 million kilometers

    • 5 million kilometers

    Correct Answer
    A. 1.4 million kilometers
    Explanation
    The size of the Sun can be measured in terms of its diameter, which is approximately 1.4 million kilometers (870,000 miles). This makes the Sun a massive celestial body, much larger than the Earth and other planets in our solar system. Additionally, the Sun's volume is about 1.3 million times that of Earth, and its mass is roughly 333,000 times that of Earth. The Sun's immense size and gravitational influence play a crucial role in sustaining life on Earth and shaping the dynamics of our solar system.

    Which of the following is NOT a primary color of light? 

    • Red

    • Blue 

    • Yellow 

    • Green

    Correct Answer
    A. Yellow 
    Explanation
    The primary colors of light—red, blue, and green—form the basis of additive color mixing. When combined in varying intensities, these colors produce a broad spectrum of hues. Conversely, yellow is a secondary color generated by mixing red and green light. This principle is fundamental to technologies such as color displays and photography. Understanding primary colors is crucial for creating accurate representations of color in visual media.
