Chemistry Essay Samples and Topic Ideas
chemistry and the modern structure of physics began. They show that there is an experiment by which it is demonstrated that we are able to perceive temperature differences, however small, thanks to our nervous system. The concepts of hot and cold were used from ancient Greece and carried out experiments that can be considered as the bases of thermometry until I appreciate the first thermoscope in the 16th century. Thanks to this, the new temperature term was reached that determines how cold or how hot a body is at a certain moment. In Mexico, the scale invented by Anders Celsius is used, which took the zero point such as water freezing and point 100 as boiling. Kelvin temperature is called the...

chemistry and Pharmacy A career that evolves to the world Biochemistry is defined as the chemistry of life, because this is responsible for studying the composition and structure of living beings (Raffino, 2018). While the pharmacy is the science of health that studies the processes of preparation of medicines for its correct use in the organism of the human being (Ecured, 2008), then the career of biochemistry and pharmacy is what allows through its studyAnalyze the composition of the human being and create medications to improve their health and as a consequence of these studies, scientific advances of great importance for the human being are obtained. Professionals studying this career are called...
chemistry, chemistry, genetics among others, so that they can help in thegenetic improvement in species. Biotechnology has had a lot Thanks to the genetic modification applied to forest species, it is observed how it is resistant to viruses, fungi, insects and resisting the application of herbicides without altering its production, having as an advantage the increase in wood production which takes the step toBetter marketing, this application is known as transgenic trees resulting in a better quality in wood, greater production. “Forest species can be incorporated genes that improve their growth and quality of their wood,” (Acuña, 2003). During an investigation carried out in countries in...

Chemistry Council, 76% of Americans throw away food leftovers every day. Besides, judging from the statistics of the leftovers thrown away and the percentage of people who throw away food each day, one would be curious to know the perception of Americans themselves. The available news indicates that significant number, 15%, of the Americans are mainly concerned about the environmental problems that are caused by this wastage as they end up in landfills and they end up becoming a major cause of environmental pollution (Snyder, 2015). It is clear from this point of view that most people who throw away are not concerned about the resources wasted but how they are affecting their environment. However,...

chemistry, oceanography, physics and biology. Nansen was trying to solve the problem of ships submerging in the ocean. He became interested the scientific observations that had been made by the challenger expedition and he further wanted to ease the sled journey they had towards the North Pole. He wanted to describe the general characteristics of the polar region covered with ice that could trap the voyages. Scientific methods such as carbon dating have been used to estimate the age of the earth. Biblical accounts have also played a significant role in gauging and estimating the age of the earth. The ever-changing estimates of the earth’s age are due to changes in some processes like sea...

chemistry, biology, and physics. As opposed to the application of single research design, experimental studies encompass a collection of strategies that utilize both controlled testing and manipulation to understand underlying courses. Typically, researchers manipulate one or more variables to establish their impact on the dependent variable. On the other hand, researchers can neither control nor manipulate the predictor variable. They usually rely on observations, interactions, or interpretations to draw their conclusions. Non-experimental researchers typically depend on case studies, correlations, or surveys. Therefore, they cannot establish an actual cause-and-effect connection. Since...
