Measurements of boiling and ice water were measured using a thermometer and measuring to the nearest degree. Mass was measured using a digital scale in grams. Volume and density were determined by using a beaker of liquid and a digital scale for liquid measurements. Voume and density of solids were determined by calculating the volume with a ruler and measuring mass with digital scale. Water displacement was measured by placing an object in a container of water and measuring change in volume.

you’re working. Next topsoil should be spread four to five inches thick, grassy areas topsoil should just be raked threw. However non-grassy areas get around five inches on top. Where there is a water runoff area topsoil should be spread seven to eight inches thick, so it won’t erode as fast as normal with water running through it. Third you would need to have more topsoil brought so that you can spread it out with the machine and make it level. Once you are done spreading the topsoil with the machine

treatment of brackish (i.e. contain dissolved salts) water supplies. Distillation is one of many processes that can be used for water purification and can use any heating source. Solar energy is a low tech option. In this process, water is evaporated, using the energy of the sun then the vapour condenses as pure water.This process removes salts and other impurities. Solar distillation is used to produce drinking water or to produce pure water for lead acid batteries, laboratories, hospitals and

dairy carbon footprint study, it showed that carbon footprint of a gallon of milk is approximately 17.6 pounds of carbon dioxide equivalents. This will usually occur during milk freight and distribution. * Water pollution-Disposal of organic wastes without treatment leads to pollution of water resources hence, causing a rapid growth of microscopic algae that kill fishes and other aquatic life. Furthermore, ammonia released from manure can lease to acid rain causing environmental harm. * Land

conclusion of the more pollution, the more the world’s temperature increases but this is all about to change. Global cooling is caused by Global Warming heating up the world and melting the ice caps. The ice caps then release fresh water, which now dilutes into the Arctic waters making it less salty. This means the Gulf Stream will no longer sink to the ocean floor and will not make its return journey to the Gulf of Mexico. As soon as the Gulf Stream switches off there is no warm air reaching the Artic

is for plants who can handle cold weathers. It is said in the article that Plant physiologists have focused on sensory systems and turgor- dependent movements that control the aperture of stomata and influence the conductance to diffusion of water vapor across the epidermis. So it somewhat stated that it focused only on such systems and movements. It didn’t entirely focus on the Plant’s components. One more thing, I can reflect that based on my readings about the article, as observed by
