bioneethub.in An English scientist John Dalton‘s developed a Law of Partial Pressures in 1801. It is a fundamental idea in the behavior of gases, particularly in the circumstance of gas mixtures. Relationship between the aggregate pressure of a mixture of non-reactive gases and the pressures of the constituent gases in the mixture is clarified by Dalton’s … Read more
An object’s movement in relation to another object is the idea of relative motion. Fundamental to physics in order to understand how objects move in relation to various frames of reference. The analysis has to use vector values for location, velocity, and acceleration when the motion is two-dimensional. Key Concepts of Relative Motion in Two … Read more
First Law of Thermodynamics provides important insight into the behavior of energy in the universe. Often known as the law of energy conservation, it basically asserts that energy can only be changed from one form to another; it cannot neither be created nor be destroyed. This law plays a vital role in the of how … Read more
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
