Evaporation

was solution volume. In order to conclude precise data over a small range, the volumes had to remain relatively constant. The most prominent source of error related to the amount of Ethanol in each solution. Because Ethanol is a volatile element, evaporation of the substance would alter the volume of a solution if exposed to air long enough. This could have caused a flaw in the chromatogram and overall Ethanol concentration. V. Experimental Questions 1. Why did you have to do an extraction on…

Global Warming: What should be done? What is global warming? Global warming is “a gradual increase in the overall temperature of the earth’s atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide chlorofluorocarbons, and other pollutions.” (Google. Global Warming) with that said I truly believe that global warming is truly a “thing” that people of all ages, race and cultural backgrounds should take serious and not ignore. With that said as a whole…

QXT2- Task 6 “No man is an island no man stands alone”, no entity on Earth can survive without interacting with abiotic factors. Organisms strive daily for survival. Their survival is predicated on receiving enough energy and nutrients to carry out metabolism and maintain homeostasis. Survival of a species is determined by the fitness of an organism within its environment and how successful it is at passing its genes on to its progeny. When examining the interactions that must be carried out…

One of the common issues within the aging population is constipation, which impacts one’s normal bowel habits and overall health. However, everyone undergoes constipation at one point in their lifetime, regardless of age. There are several causes that lead to this discomforting situation, and many individuals are not comfortable opening up about this feeling to health care providers. The purpose of this paper is to discuss constipation concerns within older adults and how nurses can promote…

Within the twenty-first century, the discussion of Climate Change is a relatively controversial topic. Scientists, politicians, and environmentalists have been debating the causes and effects of the changing climate patterns for decades. And while there has been scientific evidence that proves the existence of this very real problem, some still seem to see it as a myth or untrue. But in fact, the problem is very real. Climate change can account for many of the world’s problems. Habitat loss,…

filaments will increase in temperature. As the temperature increases, it will get hotter and hotter as the filaments draw even more power. Thus, the bulb will get lighted up. Another way is to fill the bulb with an inert gas which is to prevent evaporation of the filament and not resulting in any significant heat losses throughout the process. Nowadays, solid-state lighting has become a more popular choice as compared to the filaments light bulb that are used in the past. Many users will prefer…

preservation of DNA molecules to add a buffer such as TAE or TBE to the agarose matrix. Fluctuations in pH can cause denaturation of DNA molecules. When heating the agarose gel, it is important not to over-boil the mixture as some buffer may be lost to evaporation at high…

The automobile is perhaps one of the world’s most useful inventions. The increasing popularity of automobiles lends its way to globalization; making globalization possible. This singular system of transportation gives people, now termed drivers, the freedom to live where they want and the opportunity to travel and explore the world. Automobiles have also become a mark of one’s socio-economic status. Having more than one automobile becomes both a sign of wealth and a necessity to rural community…

As humanity has grown and expanded we have had an incredible, and arguably, irreversible effect on our biosphere. Between our intense levels of energy consumption and the pollution as a result of that use we are stretching the planet’s ability to correct itself it the limit. The Earth goes through different stages naturally, but the human race is torn between wanting to stop it, thereby keeping with what we know, and wanting to allow the Earth to right our wrongs. We are moving towards finding…

Tropical Rainforest The Tropical Rainforest is a really interesting ecosystem. Did you know that the rainforest in southern Asia stretches 3,100 miles on 20,00 islands. Did You also know that some plants in the rainforest can help treat cancer. The tropical rainforest is home to some weird and endangered animals. Location Tropical Rainforest can be located in north South America,west Africa, southern Asia. It stretches from Peru and goes through the Amazon basin to the end of east Brazil.…
