  • Common O-Level Physics Mistakes (Part 1)

    In this post, we’ll talk about some Common O-Level Physics Mistakes. Here are some questions that O-level students get wrong (Part 1). Kinetic and Potential Energy Common Misconception: Sometimes students think that an object can have only one type of energy at a time, but an object can have both kinetic and gravitational potential energy…

  • Kinetic model of matter (Solid, Liquid and Gas)!

    In this blog post, we’ll explore Kinetic model of matter (Solid, Liquid and Gas)! Besides, the fundamentals of which state have fixed shape and fixed volume, please note the following. Summary pointers: Internal Kinetic Energy of Particles: Definition: The energy associated with the motion of particles within a substance.Factors: Depends on the temperature: higher temperature…

  • Chemistry Periodic Table Trends (Down Group 1 and 17)

    This post is about Chemistry Periodic Table Trends (Down Group 1 and 17). Last week, our post was about Chemistry Periodic Table Trends (Across a Period). This week, it will be about trends (Down Groups 1 and 17). Trends Down Group 1 (Alkali Metals) Atomic Size:Trend: Increases down the group.Explanation: As you move down Group…

  • Chemistry Periodic Table Trends (Across a period)

    This post is about Chemistry Periodic Table Trends (Across a period). Across a Period: Atomic size decreases, and electronegativity and ionization energy increase. Trends:Across a Period: Atomic size decreases, and electronegativity and ionization energy increase.Down a Group: Atomic size increases, and electronegativity and ionization energy decrease. Atomic Size Decreases Across a Period:Reason: As you move…
