Introduction Copper (II) chloride is a compound with a chemical formula called $\mathrm{CuCl_{2}}$. It is one of the compounds found in rare minerals like eriochalcite and tolbachite in its dehydrated or anhydrous form. It is also often found in fumaroles. The two forms of anhydrous (dry powder) or dehydrate (moisten) $\mathrm{CuCl_{2}}$ impart two different colours - yellowish-brown and bluish-green. This compound acts as a catalyst in chemical synthesis. Another name for this compound or inorganic salt is Cupric chloride. What is Copper (II) Chloride? Copper (II) chloride is an inorganic compound with the chemical formula $\mathrm{CuCl_{2}}$. Exist in ... Read More
Introduction The no. of protons presents in the nucleus of every element's atom, denoted by the letter Z, is the element's atomic number. Using only an atom's atomic number, an element can be identified as an atom. Any atom with the atomic number 8 represents an đť‘‚ (Oxygen) atom, and a different element would be represented by an atom with a different proton no. The mass number, which is represented by the A, is neutrons plus protons in an atom. Atomic Mass It is the average mass of elements. The atomic mass, determined in amu (atomic mass unit), is equal ... Read More
Introduction The Scottish chemist Thomas Graham first put forward the systematic study of diffusion of gas molecules. He made his contributions to diffusion in the year 1828 to 1833. He observed that when different gases are brought together there is a spreading of gases instead of their arrangement in the terms of their density. So there is a spontaneous intermixing of gases taking place. And this property is diffusion. In the year 1848, Thomas Graham itself discovered the property of gas, effusion too. The escape of gas molecules irrespective of their nature happens when they are brought into small holes. ... Read More
Introduction The primary distinction between erosion as well as corrosion is that erosion relates to a physical change in matter, while corrosion refers to a chemical change in matter. Both erosions but also corrosion are natural processes with varying effects on the surfaces they interact with. Although erosion transports tiny rocks including pebbles to new locations, corrosion alters the chemical makeup of objects by causing differences in the composition of the area in which it occurs. Most often, people mix erosion with corrosion, unable to distinguish between the 2 natural processes since they share similarities. What is Erosion? ... Read More
Introduction The physical quantities which contain both magnitude and direction are called vector quantities like Displacement, Velocity, and so forth. The physical quantity which contains only magnitude is called a scalar quantity. For example, distance, speed, etc. angular speed is a scalar quantity. Measurement is the comparison of an unknown quantity with a known value. Measurement is a system of measuring. Measurement is always a numerical value. Measurements include length, mass, volume, temperature, etc. It is associated with geometry, trigonometry, algebra, etc. Units were given to the measured values. Fundamental units for length, mass, and time are m, kg, and ... Read More
Introduction Various scientists are making several attempts to measure the size of atoms. But Avogadro's hypothesis gives an important explanation for it. Avogadro's hypothesis was accepted after two years of Avogadro's death. It was accepted when Italian chemist Stanislao Cannizzaro was able to explain chemical exceptions to Avogadro's hypothesis. He explained and proved the relationship between atoms and molecules and the various weights of the materials. Now, we will discuss the Avogadro hypothesis and learn how to calculate the size of atom using Avogadro law. What was Avogadro? Amedeo Avogadro or full name Lorenzo Romano Amedeo Carlo Avogadro (Born ... Read More
Introduction When we are moving from one position to another position, then we are said to be in motion. Motion is nothing but just a movement. Every moving object's changes their position with time. Now, it is also well known that motion is of two types, Uniform and Non-uniform. Uniform motion is constant and there is no change. However, Non- uniform motion is an example of changes in motion. Now, we will learn how an object changes their position with time. What do you mean by the rate of change of motion? We know that every type of motion ... Read More
Introduction In thermodynamics and statistical mechanics, we often study gas molecules inside a container. In such a case, it is impossible to study each molecule separately. Indeed, even in a single mL of gas, there are almost an uncountable number of gas molecules. Thus, instead of working with individual molecules, we focus on them as a system. When we work with systems, we describe them by picking a range of velocities and trying to figure out the possible number of molecules that are moving with that velocity. This is where Maxwell-Boltzmann Distribution comes in handy. What Is Macrostate? To understand ... Read More
Introduction If you have spent some time around the concepts of electrodynamics, chances are that you have already come across Maxwell’s equations in one form or another. Even if you didn’t know what they were called at the time, they still must have found their way into your concepts. Maxwell’s equations form the fundamentals of electrodynamics. Along with the Lorentz Force Law, these four equations form the basis of electrodynamics, and every single problem can be tackled using these five equations alone. In this tutorial, we will discuss displacement current and Maxwell’s equations. What Is Displacement Current? You must ... Read More
Introduction Maxwell’s contributions to the fields of science span more than a single topic. The equations named after him in electrodynamics form the fundamentals of the topic, while his work on color theory is still regarded as ground-breaking. Indeed, Maxwell presented the first-ever color photography demonstration in 1861. Maxwell’s relations in thermodynamics also carry immense significance. In this article, we will discuss what these relations are, and how they can be derived. What Are Maxwell Relations? Simply put, Maxwell’s relations are a set of equations that relate the derivative of different thermodynamic quantities under different scenarios. They can be arrived ... Read More
