desalination of water water‚ desalination of‚ process of removing soluble salts from water to render it suitable for drinking‚ irrigation‚ or industrial uses. The principal methods used for desalination include distillation (or evaporation)‚ electrodialysis‚ freezing‚ ion exchange‚ and reverse osmosis. In distillation saltwater is heated in one container to make the water evaporate‚ leaving the salt behind. The desalinated vapor is then condensed to form water in a separate container. Although long

Water is also known as H2O. I am made of two Hydrogens and one Oxygen. I love to travel and can be found in every home in the United States. I can change into many different shapes and can go almost anywhere if I am given the chance. My story starts in a well in my back yard at my home. I come from an underground aquifer. I can travel through the pipes into my kitchen faucet. I have many uses. I can be hot‚ warm or even cold. I can be mixed with dish soap in the kitchen sink or ran through

Greenhouse gases are both man-made and occur naturally‚ and include a number of gases‚ including: * carbon dioxide * methane * nitrous oxide * chlorofluorocarbons * water vapour Optimal amounts of naturally occurring greenhouse gases‚ especially water vapor‚ are necessary to maintain the Earth’s temperature at inhabitable levels. Without greenhouse gases‚ Earth’s temperature would be too cold for human and most other life.However‚ excessive greenhouse gases

that will allow me to use real world items to experience and observe condensation in my own home. There will be a graph that will include the information regarding the experiment such as 1) the room temperature of standing water 2) the dew point temperature of the standing water‚ and 3) the result of relative humidity. Through this lab‚ I will learn how the changes in temperature can cause condensation to occur and how it affects relative humidity. Before completing this lab‚ one must understand

For thousands of years people lived in harmony with the environment and it seemed to them that the resources of nature had no end or limit. With the industrial revolution our negative influence on Nature began to increase. Large cities with thousands of steaming‚ polluting plants and factories can be found nowadays all over the world. The by-products of their activity pollute the air we breathe the water we drink the fields

EXPERIMENT 1: WATER CRYSTALIZATION OBJECTIVES: To determine the percentage of water in aluminium sulphate hydrate To calculate the water of crystallization for aluminium sulphate hydrate To prove that a hydrate solution will lose some of it mass after heated INTRODUCTION A hydrated salt is a crystallize salt molecule that is weakly attached to a certain number of water molecules. Salt is created when an acid’s anion (negative ions) and a base’s cation (positive ions) are combined to produce
