My Science Project Can water float on water? My Prediction I predict that water can’t float on top of water. Simply because it sounds impossible‚ but it will be interesting to find out if however it is possible. The Experiment First‚ I found two 1litre bottles and marked one with ‘+ salt’ and the other with ‘fresh’. I then went on to add red food colouring to the fresh bottle and yellow to the + salt bottle. The reason for doing so was to establish which ones were which and see if they

Blood Pressure and Pulse Determination National University Bio 202 Human Anatomy & Physiology 2 Lab Report Activity 33A Dr. Alpa Gautam March 6‚ 2012 Abstract The purpose of the paper is to inform and conduct a laboratory report on human blood pressure and pulse determination. Systolic (contraction) and diastolic (relaxation) pressures refer to the ventricular contraction and relaxation. With knowing the two pressures‚ one can distinguish if he/she is at a normal

What is Alkaline Water? Alkaline water‚ also commonly known as ionized water‚ is water that has a pH level greater than seven. This water is generally produced with the aid of a faucet-based water ionizer‚ or "alkalizer" and features a number of health benefits. Making Alkaline Water These are some of the possible sources of alkaline water: * Lemon (& Lime) Water * pH Drops * Alkalising Powder * Mainstream Water Filters * Water Distillers * Reverse Osmosis * Alkaline

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 and Electrolytes Water constitutes 50-55% of a woman’s body weight and 55-60% of man’s weight. Water gives structure and form to the body‚ helps maintain body temperature‚ and also creates the necessary environment for cell metabolism. There are two compartments of body water‚ extracellular and intracellular fluid. Extracellular fluid (ECF) is water found outside of cells. Making up approximately 20% of total body weight‚ the ECF consists

The Physical properties of water: 1. Knowledge of the physical properties of water: Water is the most abundant compound on Earth ’s surface‚ covering about 70 percent of the planet. In nature‚ water exists in liquid‚ solid‚ and gaseous states. It is a dynamic equilibrium between solid and gas states at standard temperature and pressure. At room temperature it is tasteless and odourless‚ nearly colourless with a hint of blue. Many substances dissolve in water and is commonly called a universal

Properties of Water Water is essential for life as we know it on earth. It is used by plants and animals for basic biological processes which would be impossible without the use of water. The origin of all life can be traced back to the water in the Earth’s precambrien seas. Water is also the universal solvent. It reacts with more elements and compounds than any other substance known to man. Water is a polar molecule made up of on atom of hydrogen and two atoms of oxygen. It is attracted
