    that the labeled amount is false due to the amount of empty space inside. Thus, the goal of this paper is to explore this idea and document the experimentation that follows in order to find out whether or not a bag of snack food contains its labeled amount. To begin with, the air inside packaged snack bags is important for preserving the product. The air inside the bag acts as a cushion, so that the product inside is not crushed. This is critical for when bags are tightly placed into boxes, which then deal with any possible rough handling that comes with the shipping procedures. But, the air inside the bags is not the same as the air we breathe around us. This is because of a packaging practice known as Modified Atmosphere Packaging. As the name implies, Modified Atmosphere Packaging, or MAP, is the alteration of the internal air composition of the packages. There are three main gases used in MAP; either by themselves or in combination. They are O2 (Oxygen), CO2 (Carbon Dioxide), and N2 (Nitrogen). Nitrogen is the most commonly used as it is easy and cost effective to store and purify. When the product is inserted into the packaging, nitrogen is injected in order to force the majority of the oxygen outside the bag. This method is known as nitrogen flushing. The reason why it would be beneficial to have mostly nitrogen in the bag rather than oxygen, is because nitrogen does not react with the food or carry moisture. This prevents the food from oxidizing and getting soft,…

    scientists have two major goals: detecting smaller, more Earth-like planets, and characterizing particular planets of interest. With the advent of the extremely large telescope (ELT) era soon approaching, these two goals will become increasingly intertwined as better instruments give us the power to study the atmospheres of smaller, potentially habitable planets. In the meantime we can look at the brightest targets, typically Jupiter-sized planets in close-orbits, i.e. “hot Jupiters,” with…

    Importance of the Nature Conservation Nature is constantly changing, even before the dawn of humanity. From the breakup of Pangaea to the extinction of dinosaurs, from the Sahara Pump to the Ice Age, Earth has completely changed from what it was millions of years ago. Beyond these spontaneous events, initiated by Nature itself, Humans are continuously adapting the Planet to accommodate their needs through careless interaction with their surrounding environment. The influence of anthropogenic…

    The greatness and rate of future environmental change will essentially rely on upon the accompanying variables: The rate at which levels of nursery gas focuses in our climate keep on increasing. How firmly elements of the atmosphere react to the normal increment in nursery gas focuses. Regular impacts on atmosphere and normal procedures inside the atmosphere framework. Researchers use PC models of the atmosphere framework to better comprehend these issues and venture future atmosphere changes.…

    Before taking the SoS Climate Change course I thought I had a fairly solid foundation on what factors cause climate to change and how those factors interact, how climate has changed over the past hundreds of millions of years and how scientist predict the future climate of our planet. I soon found out that I merely had a solid scaffold on which to build a much better understanding for myself and my students. The biggest take away for me was how Earth’s systems all work together and that there…

    way to prevent the burning of fossil fuels is to buy an electric car or a vehicle that burns alternative fuels such as ethanol (Coughlan 26). The reason more people are not driving these cars now is because of the price. Once more people start buying these environmentally friendly cars, the price for them will go down (34). Another way to make a difference is to be more efficient. If people tried to buy more efficient home appliances such as refrigerators, and air conditioners, it would…

    When dinosaurs ruled the earth, the climate was most likely humid and warm. The carbon dioxide in the atmosphere was close to present day levels. Scientists found that the reasons of extinction of dinosaurs have linked to the global warming. Changes in climate would have occurred due to the disruption of wind and ocean currents. These marine changes, combined with volcanism and an extraterrestrial impact, may have caused the mass extinctions. (Dinosaurs Climate Change and Biodiversity) Similarly…

    Global warming affects everyone and everything on this planet, but with so many different opinions, theories, and predictions it can get confusing to know what the primary cause of global warming is. Global warming is simply defined as 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 and other pollutants. Global warming has an overwhelming effect on plants and other organisms in the…
