Importance of Water All living things need water. The Earth is full of water. Water is the most essential element‚ next to air‚ to our survival. Water makes up more than two thirds of the weight of the human body‚ and without it‚ we would die in a few days. There are many water importances in our life to complete daily life and to maintain we body health. Humans and other creatures must drink water to avoid dehydration. Dehydration is defined as a loss or insufficient levels of water and important

2300 feet below in August‚ 2010. For about two weeks there were not any type of signs that the miners had survived. Surprisingly a small hole reached the miner’s and they sent up a message telling rescuers they were alive. These miners went on to be trapped below for two months before rescuers could reach them. They were rescued in a specially designed capsule that was a half a mile shaft. The rescue took about 22 hours. The tragic story was plastered all on the news and internet for the world to take

“WATER IS A GOOD SOLVENT” Water is very unique in all facets of its nature. The chemical formula for water is H2O as a water molecule consists of two atoms of the chemical element hydrogen (H) and one atom of the element oxygen (O). Water is the most abundant chemical compound on earth as its mass all exists together‚ naturally‚ in its gaseous‚ liquid and solid state. It is the most precious natural resource to man and is essential to life for all discovered living organisms. One of the unusual

body•External: fertilisation occurs outside the organisms bodyMany Australian organisms have produced certain mechanisms to assist in the process of fertilisation. •Sexually mature‚ gamete production and release may be stimulated by environmental factors¹. For example coral polyps off the Ningaloo Reef in West Australia‚ have cyclical breeding seasons so the female and male gametes are released simultaneously ‚ increasing the chance of fertilisation. Most aquatic organisms have external fertilisation‚ so a watery

Trapped Suddenly‚ I realize that I am trapped in a nightmare. Standing in the doorway of a building‚ a rush of damp‚ misty air hits me. I study the open door and walk forward. The door slams shut behind me‚ locking me in. The air rings with a loud metallic bang as the door hits its frame. I turn to see the rattling door seal itself. It remains locked tight‚ allowing no one to pass through; it has trapped me in‚ and forbids me to walk out. Fear paralyzes my entire body‚ and I am unable to think

Importance of Water for Living Organisms Water is made up of two elements‚ 2 positively charged hydrogen molecules and one negatively charged oxygen molecule. Water molecules have uneven charge distribution as one end of the molecule is slightly positive and the other slightly negative‚ this is called polar. Ionic substances such as sodium chloride dissolve easily in water because the positively and negatively charged ions are separated due to the dipole nature of water. As water is dipolar‚

FLUID MECHANICS Fluids mechanics is a branch of mechanics that is concerned with properties of gases and liquids. Mechanics is important as all physical activities involves fluid environments‚ be it air‚ water or a combination of both. The type of fluid environment we experience impacts on performance. Flotation The ability to maintain a stationary on the surface of the water- varies from he on person to another. Our body floats on water when forces created by its weight are matched equally

Fluid Catalytic Cracking Fluid catalytic cracking* (FCC) is the most important conversion process used in petroleum refineries. It is widely used to convert the high-boiling hydrocarbonfractions of petroleum crude oils into more valuable [1][2][3] gasoline‚ olefinic gases and other products. . Cracking of petroleum hydrocarbons for conversion of heavy fractions into lighter fractions was originally done by thermal cracking which has been almost completely replaced by catalytic cracking because
