mixture to alter the phase of the volatile substance. The researchers used the simple distillation set up to conduct the experiment. 25 ml of The Bar Vodka was used and 7 ml of distillate was collected before a temperature of 95 degrees Celsius was reached. Collected distillate was then subjected to a flammability test to confirm ethanol content. The percent ethanol was computed to be 24%. Introduction Distillation is a method of separation for homogenous mixtures‚ which are composed of both volatile

science is based on facts and theories and it reaches its results through an approved scientific method. Consequently‚ it seems to be objective and thus more truthful and reliable. However‚ other persons argue that this is a misunderstanding of science. Hence‚ one should question what science and knowledge entail. Can there actually be some form of knowledge that overrules all other types of human knowledge? Is scientific knowledge actually always objective? Are there other types of knowledge of equal

There are several methods that both measure and scan the cortical functions of the brain and they both have their individual strengths and weaknesses. In a Positron Emission Tomography (PET) scan the scanner injects the patient with glucose containing radiotracers which are radioactive and emit positrons which are then picked up by the scanner. As glucose is used for energy in the body it will travel to the brain and distributes itself to the parts of the brain need it most at that time. When it

The Scientific Revolution was a period of time when many scientific discoveries were made. The Scientific Revolution began in the 1500s and ended in the late 1700s. Many of the discoveries made during the Scientific Revolution were centered on the idea that there are certain mathematical laws that rule over and apply to the entire universe. Because of these discoveries‚ many scientists believed that we could better understand the physical characteristics of the world we live in and use them to

Throughout life‚ we all make educated guess; explaining a set of observation and derive and write and formulized hypothesis (Formalized Hypotheses example: If skin cancer is related to ultraviolet light ‚ then people with a high exposure to uv light will have a higher frequency of skin cancer). There are three types of scientific statements: there are Hypothesis‚ Law and Theory. A hypothesis will give a plausible explanation that will be tested. It can also explain future phenomenon that will need
