Thermal energy refers to the energy possessed by an object due to the movements of particles within the object. It’s the internal kinetic energy of the object, which comes from the random movements of the object’s molecules and atoms...
A mixture is a physical blend of two or more compounds. Each compound retains its own characteristics in the mixture. Scientists recognize two types of mixtures: homogeneous and heterogeneous mixtures. In the overview article, we’re going to...
Osmosis is an example of diffusion in which molecules tend to distribute themselves evenly in space. Unlike diffusion, which can take place in all mediums (gas, liquid, and solid), osmosis only occurs in liquids and (very often in) gases. What...
Kinetic energy is the energy of motion: if something is moving, it is said to have kinetic energy. According to classical mechanics, the kinetic energy (E) of a non-rotating object depends on its mass (m) and velocity (v). E = ½mv2 Since energy is a...
Nanomaterials have become a trending area in science and technology. Numerous metal nanomaterials have been extensively studied for a wide range of applications. Among them, gold nanoparticles have been found to be highly remarkable. They have...
Chemistry is the science that deals with the structure, composition, and properties of substances. It also includes studying how these substances undergo certain chemical changes and how they release or absorb energy during the transformation...
The term “forensic” is derived from the Latin word “forēnsis,” which means of or before the forum. The history of this word dates back to Roman times, during which the person accused of a crime was presented before a group of...
In chemistry, a base can be defined as a substance that dissociates in an aqueous solution to form Hydroxide ions (OH− ). A weak base is a base that doesn’t completely dissociate into its constituent ions when dissolved in a solution. Some...
A chemical change is a process in which one or more substances are converted into one or more new and different substances. These substances can be either chemical elements or compounds. Chemical changes occur as the result of chemical reactions...
A decomposer is an organism that breaks down complex organic matter from dead or decaying organisms to obtain energy. It may sound unpleasant, but decomposers do nature’s dirty work. They eliminate dead or dying organisms, and while doing so...
One may think that precipitation is just about rain, but that’s not the case. In simple terms, precipitation is any type of water particles, liquid or solid, that form in the atmosphere and falls on the earth’s surface. METAR weather...
Titanium nitride belongs to a group of refractory metals in which a nonmetallic element (Nitrogen) forms a compound with a transition metal element (Titanium). This metallic compound has a brown color and appears gold when applied as a coating. It...
