      What Causes Evaporation?

      When the Earth begins to get too hot, the water increases in temperature. As the water continues to get hotter, it begins to undergo a phase change in which water turns to gas. The water droplets turn into water vapor because the temperature has caused the individual water molecules to speed up considerably. This process

    • Anodizing Aluminum

      Anodizing Aluminum

      Anodizing/anodized aluminum refers to both a specific type of aluminum alloy as well as the process that is used to produce this alloy. The term “anodizing” is used to describe a technique for expanding the natural oxide layer of metals, especially aluminum. Anodizing changes the texture of aluminum by creating a much more porous surface

    • The Kelvin Scale

      The Kelvin Scale

      The Kelvin Scale is a thermometric scale used in physical science to describe the absolute temperature of an object, substance, or area. While Fahrenheit and Celsius scales measure temperature, the Kelvin Scale defines temperatures relative to an object’s thermodynamic movement. As a result, the Kelvin Scale does not use degrees, but simply a number followed

    • How Wireless Power Induction Works

      How Wireless Power Induction Works

      Wireless power induction is already being used today in the form of electric toothbrushes. An electric toothbrush contains coils or loops in the toothbrush handle as well as in the base recharging unit. Because of their constant exposure to water, electric toothbrushes have to use inductive coupling as a means of recharging their batteries. Inductive

    • How Sand is Formed

      How Sand is Formed

      Sand is a sedimentary material; loose grains of worn out and disintegrated rocks. Sand is of fine granules with grains ranging between 0.06 and 2.0 mm in diameter. Sand is a naturally occurring fragmented material comprised of tiny particles of decomposed rocks, shells, or corals. So how does sand come about? As mentioned before, nature

    • What is a Pitot Tube?

      What is a Pitot Tube?

      A pitot tube measures pressure levels in liquids. They are most commonly seen in laboratory settings but can be seen in industrial applications as small cylinders. While a pitot tube is not the only device that measures fluid pressure, it is capable of being implemented in much more diverse environments than similar devices. How Pitot

    • 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

    • What is a Plastic Injection Molding Machine?

      What is a Plastic Injection Molding Machine?

      A plastic injection molding machine or injection press is a device that melts plastics and materials made from other polymers, and injects them into a mold. Plastic injection molding machines are most often used to recycle plastic, but are also the primary device responsible for producing plastic objects in the first place. They use a

    • Law of Universal Gravitation

      Law of Universal Gravitation

      The law of universal gravitation gives the attraction force between two objects due to gravity. Definition: For any pair of objects, they attract each other with a force that is directly proportional to the product of the masses of the objects and inversely proportional to the square of the distance between their centers of mass.

    • What is a Polyolefin?

      What is a Polyolefin?

      One of the largest classes of organic thermoplastic polymers is polyolefin. Polyolefin is an odorless, non-polar, and non-porous material that is used in structural plastics, consumer goods, industrial products, and food packaging. Polyolefin means “oil like” and is commonly referred to as a thermoplastic or polyalkene since polyolefin has a waxy texture. This substance is
