Diffusion All these effects are due to diffusion. Diffusion is the movement of one type of gas molecules through another. Perfume through air, manure through air, food through air, copper sulphate through water and so on. Lets think about the diffusion of perfume. The molecules of air in the room and the molecules of perfume in the spray are all moving around quickly and randomly (in all directions). The molecules of perfume collide with other molecules of their own type and also with

In a dark room filled with stuffed animals, was me in my bed. Being half asleep, the illness bothered me. With fever ache and painful throat, I could barely open my eyes to feel myself. The back of my eyes balls was boiling, my throat as dry as the tree branches, I want to call for help. Help from my mother, father, anyone out there. I tried to sit up, my legs was too numb to move, every inch of muscles was stiffen, like I was mummified. The sound of the cracking stairs alarmed me; I turned my

Geothermal energy represents the inner heat of the earth, produced largely by the decay of radioactive elements in the mantle and center. The three ways that the heat is found is both wet and dry steam (wet steam has drops of water in it), hot water and dry volcanic rocks. We know that the temperature of the earth at depths of 25 to 50 km range from 200`C to 1000`C. There are areas of the earth where local concentrations of heat occur, just as mineral concentrations do. Most of these

Water Resources and Sustainability Notes Distribution of fresh and salt water around the world: - 97.5% of all water on the Earth is salt water, leaving only 2.5% fresh water. - Nearly 70% of that fresh water is frozen in the icecaps - Most of the remainder is present as soil moisture, or lies in deep underground aquifers as groundwater is not accessible to human use. - Less than 1% of the world’s fresh water is accessible for human uses and this water is found in lakes, rivers and reservoirs

James Shin Per 7b/8 Ecology Take Home Test 1) In the given info, there were two groups, an experimental and control group of flowers and sagebrush in a desert landscape that were identical except that the experimental group had a fence enclosed around it. Also, there was a predation relationship between the wildflowers and the kangaroo rats because the kangaroo rats eat wildflowers. Assuming that the fence was limiting the space of the experimental plot, competitive exclusion caused the extinction

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
