1. Introduction:- Maintenance of machinery bilges has always been a challenge to the maintainer due to poor accessibility and unavoidable effects of running machinery such as spillage of cooling sea water, spillage of fuel, spillage of lub oil, high ambient temperature and drainage of hot water below feed quality (in case of steam driven machinery). Coal tar epoxy paint (CTE) has been in use in these bilges. However the expected life of CTE could not be achieved, in many cases, as stringent surface

In the fluffy white clouds, up in the atmosphere, there once was a water molecule named Drip-drop. Drip-drop has been with other molecules for as long as he could remember. They are happily contented with just lying on their backs, soaking up the warm sunlight. Sometimes Drip-drop would sigh and hope for an adventure to come his way. “I wish there’s something else to do here,” he sometimes muttered to himself. Nothing seems to bother their simple and comfortable lives up there in the heavens until

drinking water shortage is a worldwide concern that is becoming more prevalent in even the most developed of countries. There’s a whole lot of water on Earth, something like 326 million trillion (326,000,000,000,000,000,000) gallons or about 70% of Earth, but only 2% is fresh water. About 1.6% of the Earth’s water is frozen in polar ice caps and another 0.36% is contained in underground aquifers and wells. Only about 0.0036% of our planet’s water is found in lakes and rivers. The rest of the water is either

found in all types of foods and if you’re not eating enough of these foods you can also buy some of the pills to help your body. The function of water in the body is it is used as a carrier of our essential minerals to get through the body, water removes waste products that include toxins through urine, it helps to break down the food we eat, and water is a large heat capacity which helps limit changes in the body’s temperature. Dehydration has many effects on the body which include decreased metabolism

osmosis. Based on our data, the bags that contained water at 55 degrees Celsius had a much greater rate of osmosis than the bags at 15 degrees Celsius. When the environment is heated up, reactions occur at a much faster rate. This is because the extra heat provides more energy. Increasing the concentration also increases the rate of osmosis. This is because there is a lesser concentration of water inside the bag in the 40% rather than the 15%. The water will rush into the bag at a greater rate because

freezing point of water? 2. Relevance of your testable question When salt is added to water it results in the reduction of its freezing point and the density of water increases. Freezing point depression which is a colligative property does not depend on its solute character rather it depends only on its solute concentration. 3. Literature review Entropy is frequently defined as a quantitative measure of randomness. When a solute is dissolved in a solution similar to water, the entropy of

and physical properties of the compound could then be identified and environmental hazards addressed. Questions that needed to be answered in relation to this unknown compound included: Is it a risk to people living nearby? What if it gets in the water supply? Does it contaminate the air? Is it reactive? Over a three week time-span the chemists experimented with the unknown compound to report the findings back to the community. After the unknown compound was identified, the chemists studied its properties

the following ecological problems: Saltiness, aridity and scarcity of water caused by the waste of enormous amounts of fresh water during the extraction process, heavy metals which are liberated and migrate into the ecosystem, the dislocation of thousands of tons of ore causes for sedimentation in rivers and susceptibility to both geologic and water erosion, migration of highly toxic cyanide into the subsoil and surface waters as well as the whole ecosystem, and acid drainage.

effect, or warm air rising over cold air, inherently begins to accumulate water molecules from within the air. The more moisture in the air, as a result of a higher dew point, the more water molecules there are to be lifted, resulting in the formation of a larger thunderstorm. As moisture is lifted to higher altitudes, encountering additional water molecules along the way, the molecules begin to accumulate. Eventually the water molecules will

materials and methods are used on two different simulate environments, Open Ocean and sandy beach. 50 mL of oil made from vegetable oil with a little bit of food coloring simulates the crude oil. Plastic tub with a bag and filling with 1900 mL of cold tap water simulates the ocean space. Sandy Ocean environment is the ocean space added a sand dune in one corner of tub made by a full cup of sand. In each environment, 50mL Formula 409 and 25 cotton balls are worked together to absorb the oil as much as they
