Green Energy Essay

In this lab experiment, we will be using an unknown volatile liquid in order to understand the direct relationship between the molecular weight of a gas and its vapor density, which will help us determine the molecular weight of the unknown. The necessary tools that are essential in this experiment include: a balance, watch glass, two pieces of foil (2.5x2.5 inches & 3x3 inches), boiling chips, a ring stand, a thermometer, a bunsen burner, and an 800mL beaker. During this experiment, we have to…

recycling cans means that new aluminum cans will have to be made, and to make new aluminum cans people have to dig into the earth’s crust which wastes a lot of energy and emits more greenhouse gases which helps in global warming. Recycling an aluminum can saves enough energy to power a television set for 3 hours. This is a huge amount of energy preserved. This shows that what we are doing is important because…

Smet Hall. The concept that I will discuss regarding my photo is thermodynamics and transfer of heat. Specifically, I will be discussing conduction from the temperature outside of De smet and the temperature of my dorm room. The material that the energy will transfer through is the two large two-paned windows that are on each wall. I will complete example calculations by measuring the calculating the area of the windows and the temperature inside and outside. During the cold Spokane morning, my…

(e) Dalton’s Law Challenge Question: Ordinary air contains about 78% nitrogen, 21% oxygen, and small amounts of several other gases. As a diver descends, the pressure of the air he is breathing increases by about one atm for every 10 m of depth. Oxygen may become toxic and cause convulsions if it is breathed at a pressure above 1.4 atmospheres. According to Dalton’s Law, at what depth should a SCUBA diver be concerned about oxygen toxicity if he is breathing ordinary air? Discussion Points: •…

most of the topic are presented as a base for questions that lead to the meat of the topic. One example was that question of ``What is the original source of energy in our body?``, from the topics we learned we have to make a connection through different things to get our answer. As we need to understand that energy in our body is ATP, the energy that cells use, is produced by cellular respiration. Cellular respiration requires oxygen and glucose to happen. From that we can see that ATP is…

The water bottle rocket was to help us on our engineering skills. It was a fun project and I’m glad Coach Rob let us do it. Me and Dylan’s rocket was a great rocket except it flew on top of the gym. It flew an altitude of 87.41ft. which was ok. I thank it would have flown better if we have had a longer nose and bigger fins. The longer nose would have made it more top heavy. The bigger fins would have had a better base on it. I also made my own rocket and it flew really good. It was a 2-liter…

According to numerous bodybuilding.com the top three supplements on the market right now are creatine monohydrate, caffeine, beta-alanin5. Creatine monohydrate is known as creatine is considered one of the most effective performance supplements that improve high-intensity work capacity, muscle mass, strength, and body composition5. Creatine increases phosphocreatine stores within the muscle, allowing an increase in regeneration of ATP5. Creatine(s) effectiveness based on scientific evidence…

Making a video for marketing project can be difficult: getting students to participate, having a crystal clear concept to make an effective ad etc. Last year, I took a marketing management course where our teacher assigned the students a class project; the class project was about making a presentation and ad, coming up with our own brand name and packaging. Since it was a mega project for the whole class, it was difficult for everyone to even where to start from. Our teacher did give some hints…

into the umbra, leaving a bright dot. Similarly, the filament indicated by a green circle evolve and disappear. The filament shown by the yellow circle also shows similar evolution, but an another filament evolve from it. Figure 3 illustrates the evolution of such filaments from another part of the time series. Cyan and yellow circles indicate the evolution of broad filaments. Evolution of thin filament is indicated by a green circle. Close inspection of the movie shows that this pore sustains…

Since the naming of the dinosaurs in 1842 it has been thought that their metabolisms were similar to current day ectothermic, cold blooded reptiles., In the 1960’s- 1970’s; however, it started to become apparent that an endothermic metabolism (warm blooded, like mammals) is more conformable with new evidence and observations. Originally, predictions on the paleothermometry of dinosaurs was based on the physical performance such as the estimation of running speed from trace fossils as well as…
