of sucrose in the dialysis bag emerged in distilled water and the potato cores emerged in concentrations of sucrose. The data reinforces the principles of Osmosis and Diffusion‚ and in a biological context‚ we can simulate how water and particles move in and out of our own cells. Introduction Objective: 1. Investigate the process of osmosis and diffusion in a model of a membrane system. 2. Investigate the effect of solute concentration on water potential as it relates to living plant tissue.

Water purification is the process of removing undesirable chemicals‚ biological contaminants‚ suspended solids and gases from contaminated water. The goal is to produce water fit for a specific purpose. Most water is purified for human consumption (drinking water)‚ but water purification may also be designed for a variety of other purposes‚ including meeting the requirements of medical‚ pharmacological‚ chemical and industrial applications. In general the methods used include physical processes such

Over Population The world’s population is approximately 5.9 billion‚ and it is still growing. It has just about doubled in the past forty years. We are now faced with the issue of over population. The problem is very severe‚ and important. It is controversial how many people this planet can hold. Some are arguing that we have plenty of room‚ and we could fit everyone on the state of Alaska‚ if we just put 10‚000 people on each square mile. Alaska only makes up about one

Effects of wind-loading on bridges Wind Loading Wind is a word that used to describe the motion of the air. It is the natural phenomenon which caused by temperature differential that is resulted from solar radiation. A moving wind that comes in contact with a solid structure will be distracted. Although the wind structure is not fully stopped‚ it still loses some of its velocity. This is due to the frictional force faced by the wind flow and the surface of the bridge. This phenomenon is actually

The purpose of accelerated bridge construction is to ensure the project planning‚ procurement‚ and logistics approach are modified to ensure tasks with long lead times‚ traditionally completed onsite‚ are of highest priority and completed using creative solutions. Multiple scenarios require the need for accelerated bridge construction technologies; where a bridge is being constructed or reconstructed over an existing roadway in use‚ where a bridge is being reconstructed or replaced for an existing

Deionized Water vs. Distilled Water Deionized and distilled waters are both processed forms of water. Deionized water is produced by filtering water to the point where it is free of ions. This ion-free water will strip ions from surrounding material‚ acting like a super-solvent. This is often used in semiconductor and other high-tech processing as a "soft" solvent and relatively cheap cleaning fluid. Distilled water is most often produced by vaporizing less pure source water (tap‚ salt or even
