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 the

Before I came to the concentration camp‚ it was easy to be with your family but I have been in the concentration came for almost 3 months. In the times I been in the camp‚ I met my best friend‚ Graciela. Ever since I been in the concentration camp‚ life has been hard for everyone. In the mornings‚ you are awakened by the kapos in the 4 in the morning where you must raise and find your shoes to work. If someone stole your shoes‚ the person who took them often means they are send to death

Internment Camps vs. Concentration Camps There were two types of camps during WWII‚ internment camps and concentration camps. They each were created in a different place‚ the United States‚ and Europe. They have many differences‚ but also some similarities. Internment camps were created in the United States. They were created for the purpose of containing Japanese-Americans. The United States became fearful after Pearl Harbor got attacked by Japan‚ so they created these camps. The camps were like

Aim: This experiment will aim to show how the amount of substrate affects the rate of the reaction. Hypothesis: In this experiment I think the amount of substrate will simply increase the reaction. As I increase the surface area of the potato the gas given off from the reaction will increase. Therefore to sum things up‚ my hypothesis is when the Independent variable increases so will the dependant variable. Independent variable: - Surface area of potato Dependant variable: - Gas Controlled

Research Paper Concentration Camps The years 1939-1942 marked the expansion of the concentration camps system. The concentration camps took in Jew prisoners for economic profit. The concentration camps also became sites for the mass murder of small targeted groups by the Nazi authorities. The concentration camps were a major role in the Holocaust‚ changing the lives of every Jew‚ leaving a horrible memory for those who did survive the concentration camps. The first concentration camp was camp

third reaction involves molecular iodine becoming a dark blue starch;I2(aq) + starch blue-black complex3. These three reactions react in a sequence. In any reaction the concentration is exponentially related to the rate of the reaction. The rate of the reaction is dependent on potassium iodate4. Therefore as the concentration increases‚ the rate of the reaction also increases. Since the rate of the reaction is inversely proportional to time‚ as the
