Centrifuge Developed by Gustaf de Laval 1879 Centrifuge is a device in which solid or liquid particles of different densities are separated by rotating them in a tube in a horizontal circle. The dense particles tend to move along the length of the tube to a greater radius of rotation‚ displacing the lighter particles to the other end. English military engineer Benjamin Robins (1707-1751) invented a whirling arm apparatus to determine drag. In 1864‚ Antonin Prandl invented the first dairy centrifuge

The purpose of this lab was to observe how molarity concentration affects diffusion.The lab was primarily based on osmosis and diffusion. Diffusion is when the movement of molecules from a high concentration that go to a low concentration to a high concentration to eventually reach an equilibrium. Osmosis is when water will diffuse from high water concentration to low water concentration to reach equilibrium. When the solutions are different the lower concentration solute is hypotonic while the higher

The gender pay gap is a very wrong rule that is present in developed countries. Women that are equally trained and educated that have the same experience as men are not getting equal pay. This rule comes with consequence for people. People have tried to close the gap and it is slowly working. The gender pay gap is present in developed countries. In the USA for example‚ if a Man and a Woman attend a university and do the same major and pick the same kind of job on average the woman will earn 82 cents

permeable membrane through a process of diffusion. The movement of a solute through this membrane is called dialysis . Diffusion is a form of passive transport. It is the movement of molecules from areas of higher concentration to those of lower concentration‚ until there is an even concentration. This movement is random because it is a result of kinetic energy. Diffusion is a slow process‚ but there are many factors that will affect it’s rate. The rate of diffusion will vary depending on the size of
