    • Potassium Carbonate Dihydrate

      Potassium Carbonate Dihydrate

      Potassium carbonate dihydrate (K2CO3.2H2O) is a white chemical. Salt from potassium carbonate and water from the dihydrate are mixed into a deliquescent (wet salt). It is a strong alkaline solution that garners a variety of uses. The salt tastes like salt and alkaline material. Potassium carbonate dihydrate is generally used as a nutritional supplement in

    • Molality

      Molality

      Molality is the number of moles in a solute per kilogram of solvent. It is often confused with the term molarity, which is an alternative unit for concentration that measures the number of moles of solute per liter of solution. Molality is commonly used when experiments require significant temperature changes. This is because a solute’s

    • What Are Pennies Made Of?

      What Are Pennies Made Of?

      Before 1982, the penny was made of copper which is why they, unlike most other coins, don't look silver. However, after 1982, the U.S. government realized that it was too expensive to make a penny–more than the penny was worth in money–so they decided, instead, to make it with a mixture of two different metals.

    • What is Magnetic Wire?

      What is Magnetic Wire?

      Magnetic wire is a copper or aluminum wire that produces an electromagnetic field when wrapped into a coil and connected to a power supply. It is used in a number of applications and is a vital component in many different devices. Magnetic wire can be used in electrical to electrical, electrical to mechanical, and mechanical

    • Laser Distance Measurement

      Laser Distance Measurement

      For the past two decades, lasers have been used to measure distance without having to physically touch the area or things being measured. Laser measurement is capable of very precise and quick distance measurements. Lasers have been used in military targeting, criminal investigations, and sports. As research has progressed, the size of laser measuring devices

    • Intelligent Transportation Systems

      Intelligent Transportation Systems

      Intelligent transportation systems are projects that aim to integrate modern communication and information technology into existing transportation management systems in order to optimize vehicle life, fuel efficiency, safety, and traffic in urbanized cities. The need for intelligent transportation systems stems from the fact that traffic congestion has been increasing all around the world because of

    • How Do Tsunamis Form?

      How Do Tsunamis Form?

      A tsunami is formed when there is an earthquake, volcanic eruption or, more rarely, a landslide underwater. Typically, neither the earthquake, eruption or landslide are felt because they are so deep under water. However, the actions that have taken place are the first steps that lead to a massive tsunami that can cause tremendous damage

    • How Safes Are Made

      How Safes Are Made

      Known under the generic name of safe or safe box there is a very broad set of constructions. From simple home safes used to keep personal documents, to bank safes which include special building construction and security measures. All safes are sturdy constructions made of metal (most with different layers) and a removable part (or

    • What is Luminous Flux?

      What is Luminous Flux?

      Luminous flux (luminous power) is the measurement of the (perceived) power of light. It is adjusted to take the human eye’s sensitivity to the different wavelengths of light into account. Luminous flux differs from radiant flux in this manner, since radiant flux is a measurement of the total power of light emitted independent of wavelength.

    • How Does a Segway Work?

      How Does a Segway Work?

      A Segway is a vertical, mobile vehicle that is able to carry a single person between distances. While a bicycle consists of two wheels and a horizontal frame, a Segway consists of two or four wheels and a vertical frame that balances atop these wheels to steady the rider. Segways run on purely electrical energy
