Engineering a Sustainable World: What Does It Take to Come Out on Top? The modern lifestyle, full of one time use items and pollution generating machines, harming our environment is common knowledge, and, without a plan, the death of our planet is certain. Environmentalist and author, Derrick Jensen uses a comparison of possible outcomes to persuade his readers to take action that would help stop climate change; political resistance is his preferred and recommended course of action for his readers

Kaylyn Nelson Mrs. Parsons English 11 January 4, 2017 Important Factors Needed in Life Respect, responsibility, and effort are all common factors you need to be successful in life. If you don’t respect others there is a great chance that you won’t be successful in your work. You need to be responsible because if you are then you also won’t be successful in your work or in school or even anything you try to do. Always put in effort towards what you need and want to do in life or how do you expect

Sports are more than just an opportunity to go outside and burn off some energy. They are more than just a way to get in shape and maintain a healthy lifestyle. Athletics are a metaphor for life that not only teaches players about the game, but helps them discover important aspects about themselves. At a young age, I did not realize all the beneficial life lessons that the world of sports has taught me, but as I experience high school athletics, I cherish the advice the game shares with me. Since

All of my life I’ve had to learn to be a hard worker. My family would never let something just be handed to me. Growing up, I’ve had to earn any privilege I wanted, such as a cell phone. My family members are all hard workers and that has carried on to me. Hard work is very important to my family and I. Hard work is not just doing the bare minimum for a job or goal, it is instead putting in all the effort someone has to get it done to the best of their ability. The amount of effort and time

Chemical reactions usually involve the absorption or release of energy, often as heat. When a chemical reaction occurs at constant pressure, the energy released is equal to the heat flow and is known as enthalpy. Heat is a form of energy that flows into or out of a system because of temperature differences. If a reaction releases heat, it is exothermic; if a reaction absorbs heat, it is endothermic. The enthalpy change of a reaction is measured using a calorimeter, an insulated device that prevents

An Analysis into how Degrees of Unsaturation of Hydrocarbons impact the enthalpy produced in a Combustion Reaction Aim To investigate the relationship between the degrees of unsaturation (DoU) and the amount of enthalpy, in a combustion reaction and to subsequently, determine whether a hydrocarbons hydrogen deficiency increases or decreases the enthalpy of a reaction. Hypothesis It is hypothesised that a hydrocarbon with a lower DoU value will produce more heat energy and, therefore, will have

William Thomson also known as Lord Kelvin, is a chemist that is famous for Devising the absolute temperature scale, now called the Kelvin scale. He also formulated the second law of thermodynamics. Thomson was given a good education at home by his own father. Thomson was the second child out of four children. Also, his mother passed away when he was at the age of six. Thomson suffered from heart problems at the age of 9 and even came close to death. Thomson’s biggest contribution to his area of
