A chemical reaction has occurred and the substances have changed their chemical makeup. The formation of rust is a chemical change. Physical Change Example Physical changes occur when substances change shape or form. Consider an icicle that formed in the middle of the night. During the day, ...
Three causes of chemical weathering are the chemical makeup of the material or substance, the climate in which the material or substance lives, and the amount of water or oxygen that the material or substance comes in contact with. What is chemical weathering? Chemical weathering breaks down roc...
One of polyaniline’s greatest advantages is that scientists can tweak its chemical makeup and the amount or type of doping to adjust its properties, making it more conductive, more flexible, or easier to dissolve, depending on the intended use. Applications Polyaniline’s many applications are ...

The machinability of the metal will vary depending on the makeup of the base material. Fotofab offers etching of Steel (1010, 1008), Electrical/Silicon Steel (M19, M36), andSpring Steel(1050, 1074, 1095). Fotofab’schemical etching processproduces designs that can withstand harsh indoor and ...
The Make-up and Quality of Steel Powders Steel powders made use of in 3D printing are normally composed of alloys such as stainless steel, titanium, aluminum, and nickel-based superalloys. These materials have unique buildings that make them perfect for additive production. High purity and consist...
A physical change is when the physical properties of a substance have changed, but the make up (formula) of the substance does not change. For example, water changing to ice is a physical change. The physical properties of ice (such as density, hardness, index of refraction) are different...
We applied our stain remover spray on a dirty white sports uniform with makeup stains and a shirt splattered with tomato sauce and oil. Finally, we tested our upholstery cleaner on a rug and sofa in a pet-filled household to assess its ability to remove lingering odors and stains. ...
