Diffusion and Osmosis Introduction: Purpose: 1. To simulate and observe the diffusion of solutes and the osmosis of water through a semipermeable membrane through color change and sugar tests. 2. To speculate osmosis occurring in dialysis bags and potato cores by comparing percentage change in masses. Background information: Molecules are always in random‚ constant movement due to their kinetic energy. This causes the molecules of a cell to move around and bump into each other. The random movement

vacation I am always ready to go! Vacation is a time for shopping‚ fun and relaxation. Some of my favorite vacation destinations include the Las Vegas strip‚ New York City and of course the beach in Destin‚ Florida. There is one thing about Vegas‚ you will never be bored.

1. INTRODUCTION OF POTATO CHIPS: Potato chips also called as potato crisps were invented in the year 1853 by Native American George Crum. The story behind the invention goes like this. George was employed as a chef at an elegant resort in Saratoga Springs‚ New York. One dinner guest felt George’s French fries too thick for his liking and rejected the order.

Plan a Menu There are different types of menus that offer different selections. Some offer many different options while others are set items.

Abstract The purpose of this experiment was to test different solute concentrations on the rate of osmosis. Artificial cells were filled with different solute concentrations and placed in water and weighed at equal time intervals to show how the water moves across cell membranes and down its concentration gradient into the lower concentrated area. The weights of the cells were recorded each interval‚ and then the rate of osmosis was found by calculating the corrected cumulative change in weight

The energy for the battery comes from the chemical change in the zinc when exposed to the acid and potato. The zinc is oxidized inside the lemon‚ exchanging some of its electrons with the acid in order to reach a lower energy state and the energy released serves as the power. The reason is that there is no such thing as electricity found in fruits‚
