The fractional distillation mixture separation process separates mixtures that have different melting points. - Isotopes are atoms that have the same number of protons or same atomic number. However, it has different mass number. - hydrogen,
Since its inception, cinema has evolved a lot, gaining sound, colors and special effects. The latest news is 3D movies, which need special glasses like the ones below to watch. In 3D movies, scenarios, people, and even cartoon characters can be viewed three-dimensionally, as if they were real and closer to us.
When light passes through a prism, its spectrum is divided into seven monochromatic colors, as a rainbow of colors arises. The atmosphere plays the same role as the prism, acting where the sun's rays collide with air, water and dust molecules and are responsible for the dispersion of the blue wavelength of light.
This law describes the quantities that influence the electrical resistance of a conductor, as cited in its statement: The resistance of a homogeneous conductor of constant cross section is proportional to its length and the nature of the material of its construction, and is inversely proportional to the area of its cross section.
Electrolysis Laws The laws governing electrolysis are the laws that relate the masses of substances produced in the electrodes and the amounts of energy spent on electrolysis. These laws were established by the English physicist Michael Faraday in 1834. First Electrolysis Law or Faraday Law "The mass of the electrolyzed substance in any of the elements is directly proportional to the amount of electrical charge that goes through the solution.
Niels Henrik David Bohr was born in Copenhagen, Denmark, on October 7, 1885. He was an important physicist who studied atomic structure and quantum physics. His father (Cristian Bohr) was a teacher and his mother was from a Jewish family. As a student, he participated in a promotion at the Copenhagen Academy of Sciences.
