In this article, we explore some fundamental physical properties of liquids and gases, which are collectively known as fluids. The defining characteristic of fluids is their ability to flow, setting them apart from solids in a crucial way. Both liquids and gases are omnipresent in our environment. Earth itself is surrounded by an atmosphere composed … Read more
Electrical power is the result of electrical energy. When an electric current flows through a circuit, it performs work. This work creates power, which can then be stored and used as energy. Electrical power is similar to mechanical power, and they can be converted from one form to another. In this article, we will explore … Read more
An atom is the tiniest part of any element. It contains smaller particles called subatomic particles. The most important of these are electrons, protons, and neutrons. These particles give the atom many of its key properties. The discovery of electrons, protons, and neutrons came from several interesting experiments. In this article, we’ll explore how these … Read more
Everything in the universe is made up of matter. Matter itself is made up of tiny particles called atoms, which are the basic building blocks of chemistry. Each atom is made up of three smaller particles: protons, neutrons, and electrons. In this article, we’ll focus on protons. Protons are subatomic particles found in the nucleus, … Read more
Isobars are elements that share the same mass number but have different atomic numbers, meaning they have distinct chemical properties but identical physical properties. The variation in their chemical properties arises from the different number of electrons in each element. The term “isobars” was introduced by Alfred Walter Stewart in 1918 and comes from the … Read more
The Atomic Number is what makes an atom unique. It’s one of the most basic and important features of an atom. In this article, we will learn about the meaning of atomic number, mass number, and the differences between isotopes and isobars. We’ll also explore the different isotopes of hydrogen and their special traits, along … Read more
In Physics, it’s important to understand how materials behave. This behavior depends on the number of tiny particles, like electrons, protons, and neutrons, in their atoms. Elements that have the same number of protons and electrons but a different number of neutrons are called isotopes. Some isotopes occur naturally, while others are made by humans. … Read more
Radioactive carbon, particularly carbon-14, is an isotope of carbon that undergoes radioactive decay.
