A particle is on equilibrium state when the forces acting on it are balanced, means that there is no net force or change in motion. A particle needs all forces acting on it to be added up to zero for equilibrium.Equilibrium can be two type: Static Equilibrium:- When all the forces acting on a particle … Read more
Energy needed to break one mole of bonds in a chemical bond in the gas phase is called bond energy, referred as bond dissociation energy. It is a basic idea in chemistry, especially when studying thermodynamics and chemical bonding. Bond energy explain, how chemical bonds form, break, and affect the stability and reactivity of molecules. … Read more
Dimensions of physical quantities is essential to derive equations, validating the consistency of physical laws, and streamlining and resolving issues in the study of physics. Dimensions helps the students in ready for more advanced physics coursework by providing a foundation for understanding the mathematical framework that describes the physical world. What are Physical Quantities? Measurable … Read more
An important idea, how atoms interact with electrons is called electron gain enthalpy. It clarifies why certain elements more readily produce negative ions, or anions, than others. Here we shall discuss in a concise and clear explanation of electron gain enthalpy, covering its importance, periodic table trends, and practical applications in chemistry. What is Electron … Read more
Law of Conservation of Linear Momentum is essential to understand how moving things behave. It says that if there are no outside forces operating on an isolated system, the system’s total linear momentum stays constant. This law, has many applications in mechanics, collisions, and based on Newton’s equations of motion. Collision Momentum Product of an … Read more
How electrons behave inside in the atoms is essential to understand the interesting field of quantum mechanics. Four quantum numbers are used to define the energy and location of an electron in an atom, spin quantum, primary quantum, azimuthal quantum, and magnetic quantum number. A complete picture of the electron’s state and behavior within the … Read more
1 Which of the following is a scalar quantity? (a) Displacement (b) Velocity (c) Speed (d) Acceleration Answer: (c) Speed Explanation: Speed is a scalar quantity because it has magnitude only, whereas displacement, velocity, and acceleration are vector quantities with both magnitude and direction. 2. The area under a velocity-time graph represents: (a) Acceleration (b) … Read more
Analogous idea is a basic concept that is necessary to understand a mixture of chemical reactions, stoichiometry (stoichiometry as the calculation of products and reactants in a chemical reaction. It is basically concerned with numbers.) and titration (titration is a chemical technique used to determine the concentration of a substance by adding a known quantity of … Read more
An object thrown into the air and moving under the influence of gravity is called projectile motion. This motion has two dimensions, vertical and horizontal. In subjects like physics, engineering, athletics, and even space exploration, projectile motion is crucial. Components of Projectile Motion There are two different components of an object’s motion when it is … Read more
Thermodynamic variable that is crucial for forecasting the spontaneity of chemical reactions is Gibb’s Free Energy (G). This was discovered by American physicist Josiah Willard Gibbs, and uses the system’s temperature (T), entropy (S), and enthalpy (H) to determine that a reaction will occur spontaneously or need outside energy In simple form, Gibb’s Free Energy … Read more
