    • Aspirin
    • Penicillin
    • Streptomycin
    • Tetracycline
    The correct answer is Penicillin.
    Alexander Fleming discovered penicillin in 1928, which was the first antibiotic and revolutionized medicine by treating bacterial infections.


  1. What is the name of the phenomenon where light is bent when it passes through different mediums?
    • Reflection
    • Interference
    • Refraction
    • Diffraction
    The correct answer is Refraction.
    Refraction is the phenomenon where light changes direction when it passes through different mediums, such as air to water, due to a change in speed.
  2. Which scientist is known for his discovery of the laws of motion?
    • Johannes Kepler
    • Albert Einstein
    • Galileo Galilei
    • Isaac Newton
    The correct answer is Isaac Newton.
    Isaac Newton discovered the laws of motion, which are fundamental principles in physics that describe the relationship between the motion of an object and the forces acting on it.
  3. What element did Marie Curie discover that led to her winning two Nobel Prizes?
    • Uranium
    • Polonium
    • Plutonium
    • Radium

  1. What is the name of the process by which a solid turns into a gas without passing through the liquid phase?
    • Condensation
    • Evaporation
    • Sublimation
    • Melting
    The correct answer is Sublimation.
    Sublimation is the process by which a solid turns into a gas without passing through the liquid phase, such as when dry ice turns into carbon dioxide gas.
  2. Which scientist is known for his work on the periodic table of elements?
    • Dmitri Mendeleev
    • Henri Becquerel
    • John Dalton
    • Antoine Lavoisier
    The correct answer is Dmitri Mendeleev.
    Dmitri Mendeleev is known for his work on the periodic table of elements, which organizes chemical elements based on their atomic number, electron configurations, and recurring chemical properties.
  3. What is the name of the smallest unit of matter that retains the properties of an element?
    • Molecule
    • Proton
    • Electron
    • Atom
    The correct answer is Atom.
