What does specific heat 4 200 J of heat needs to be supplied to 1 of water 4 200 J kg-1°C-1 kg of water to produce a 1 °C temperature mean? increase. 6. The physical When two objects of equal mass are heated at meaning of equal rates, the object with the smaller specific specific heat heat capacity will have a faster…

South, East, and West without the slightest aid. I can always sense where the ocean is when it is out of sight (and will usually be found staring in that direction when I am bored). I can identify and differentiate wind and current lines on the water with only a glance. When I mention that I am a sailor to my friends, their minds usually conjure up images of boats cruising around on a relaxing Sunday afternoon in the bay for a few hours. In my case, I have been competitively racing sailboats…

Climate changing is affecting the way 5.2 million American Indians and Alaska Natives are living, 1.1 million of them on reservations or native lands. As these indigenous people are already profoundly poor, the fluctuations climate change brings, hits them even harder. Food and drink which are simple for us to get, is not for them. Food like salmon, shellfish, marine mammals, and the conventional crops are becoming more difficult to produce or find, which hurts these people economically,…

is second hand smoke in restaurants. As reported by the American Lung Association, a significant source of premature deaths and diseases in nonsmokers is exposure to second hand smoke (American Lung Association 2015). While many states have passed laws prohibiting smoking in the entire restaurants, there are still some locations where they still allow a smoking and nonsmoking section. The smoking/nonsmoking sections in most cases are separated by a half wall or a large amount of space, but…

gas exerts force on the walls of a container, this is known as its pressure. Pressure varies based on temperature and volume. Many gas laws were used within this experiment, such as the Ideal Gas Law, Boyle’s Law, Charles’s Law, and Avogadro’s Law. The Ideal Gas Law is simply the combination of all the simple gas laws, Boyle’s Law, Charles’ Law, and Avogadro’s Law [which combines all of the properties of a gaseous sample].2 Boyle’s…

source of error is the fact that the standards used to make the standard curve did not have the same ingredient as the Gatorade. In addition to the dye, Gatorade consists of sugar, salt, citric acid and other ingredients. The standards simply contained water and dye but did not account for all these other ingredients. Ingredients such as sugars, salt, and citric acid could influence the amount of light that passes through the solution and thus alter the amount of light received by the photometer…

Mangroves are the typical coastal ecosystems stand out as a distinct forest type at the interface between terrestrial, estuarine, and near-shore marine ecosystems, where sea water and fresh water mixes and creates the favorable salinity condition for the mangrove species to grow. Mangroves have special adaptability to grow in such harsh environment; also, it provides massive ecosystem services to the coastal communities (Yusuke et al, 2012). However, mangrove species are increasingly threatened…

heavily-used water source, is home to a variety of fish and a supplier of over 70% of the drinking water in metro Atlanta; it was also ranked number three on America’s ‘most endangered’ list. Each day, more than 250 million gallons of sewage waste water is dumped in to river, so news that the river is constantly contaminated with E. coli is no surprise. Even with the vast amount of contamination, Georgia allows the dumping of waste to continue; they give out permits to dump in the waters.…

Water contamination from fracking According to American Rivers, fracking threatens rivers and streams that provide clean drinking water, habitat for fish and wildlife, and recreational opportunities, such as fishing and boating. Many of America’s greatest rivers are under threat from natural gas development. They include…

whenever two chemicals react together you can’t lose any of the atoms. So lets say you have a chemical reaction of H2O + NaCl, which is water and table salt, it could go to NaH2 +ClO, but it can’t lose any of the atoms it started with or gain any new ones. The Law of Conservation of Mass governs how a chemical reaction happens because if the chemical reaction of water and table salt happened and it lost a hydrogen atom, it could make something completely different and the physical properties…
