Temperature is a physical quantity that expresses quantitatively the perceptions of hotness and coldness. Temperature is measured with a thermometer. Thermometers are calibrated in various temperature scales that historically have
A covalent bond is a chemical bond that involves the sharing of electrons to form electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs.
An atom is a particle that consists of a nucleus of protons and neutrons surrounded by a cloud of electrons. The atom is the basic particle of the chemical elements,
Force in physics is the push or pull on an object that causes it to change its velocity or direction123. Force is a vector quantity, meaning it has a magnitude
For a science student, having the right tools and materials in their bag can significantly aid in studying, experimenting, and understanding scientific concepts. Here are some basic essentials a science
Gratitude builds a bridge to abundance.
“The only way of discovering the limits of the possible is to venture a little way past them into the impossible.” ― Arthur C. Clarke
Units of measurement are standardized values used to express various physical quantities. They provide a consistent and universally accepted way to describe the magnitude of different properties. Here are some

“Believe in yourself. You are braver than you think, more talented than you know, and capable of more than you imagine.” ― Roy T. Bennett, The Light in the Heart
Fission is the process utilized in nuclear power plants to generate electricity, where controlled nuclear reactions are used to produce heat that boils water and drives turbines to generate electricity.
The enthalpy of a chemical reaction, often denoted as ΔH (delta H), is a measure of the heat energy absorbed or released during a chemical reaction at constant pressure. Enthalpy
“Spacetime tells matter how to move; matter tells spacetime how to curve.” ― John Archibald Wheeler, Geons, Black Holes and Quantum Foam: A Life in Physics
In order to succeed, your desire for success should be greater than your fear of failure. ― Bill Cosby
