A base, in chemistry, refers to any substance that releases hydroxide ions (OH−) when dissolved in water or an aqueous solution. Many bases, however, don’t readily carry hydroxide ions, but they, too, produce high levels of OH− when...
NASA is the gold standard in human space exploration, engineering excellence, and scientific discovery. Its influence extends far beyond American borders. NASA has shaped the modern space industry, spurred international collaboration, and...
If you ask any random person what the hardest material on Earth is, the most likely answer would be diamond. It is fairly common knowledge. But is diamond actually the hardest material or mineral on Earth? We’ll find out in this article. How...
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, when the person accused of a crime was presented before a group in the...
Chemistry is the science that deals with the structure, composition, and properties of substances. It also includes studying how these substances undergo specific chemical changes and how they release or absorb energy during the transformation...
Benjamin Franklin gets all the credit for discovering electricity, but all he did was establish a link between lightning and electricity. Charles François Fay, Luigi Galvani, Alessandro Volta, Michael Faraday, Thomas Edison, and Nikola Tesla...
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...
The new plasma accelerator can generate electron beams with energies up to 7.8 billion electron volts in just 20 centimeters. This is almost double the previous record for energy generated by plasma acceleration (set in 2014). To...
The World Meteorological Organization recognizes more than a hundred different types of clouds. However, they can be categorized into 10 main types based on their overall shape and the altitude where they form. Clouds are classified and named using...
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...
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...
