Gases

hydrosphere. Without the hydrosphere many forms of life would not be able to exist including humans. It provides a place for animals and plants to live. Another important sphere is the atmosphere. The atmosphere is the blanket of gases surrounding the Earth. It is made up of three gases including nitrogen (78%), oxygen (21%), and argon (1%). The atmosphere makes the Earth livable, it protects the Earth from some of sun’s dangerous rays, and traps heat keeping the Earth a comfortable living…

Whether it be the gasoline our cars utilize or the electrical currents that power our phone, everyone uses energy in some form. Most of the time, the energy being used are fossil fuels, e.g., crude oil, natural gas, and coal. Despite the wide audience that reap the benefits that fossil fuels provide, they actually do more harm to the Earth than most people think. 85% of America’s fuel usage comes from fossil fuels. The usage of fossil fuels do provide immense amounts of energy throughout…

produce electricity, and steam, supplementing coal and other fossil fuels(Chiras, 1989, pp. 271-272). Many energy sources today struggle to control their CO2 emissions, as these can cause harm to the ozone layer and increase the effects of greenhouse gases, potentially warming the planet. Biomass, for the most part, creates no harmful CO2 emissions. Biogas Biogas is a gaseous mixture that is about two-thirds…

The Greenhouse Effect - What is the greenhouse effect and why is it important? “The greenhouse gases absorb some of this energy and radiate much of it back towards the surface whilst the rest is radiated out to space. This plays an important role in keeping the Earth 's surface warm and able to sustain life.” Step 1: How much energy from the sun hits the earth and what determines the amount? Based on the energy coming in, what should be the average intensity of the energy leaving the earth? The…

was found by calculating the density and molecular size of water molecules. Finally, the molecular size in solids was found by measuring the dimensions, mass, and volume of a dry ice sample. Then, this sample was used to find the molecular size of gases through the sublimation process of dry ice. Through this experiment,…

Climate change is an extraordinarily important problem, and requires immediate and radical government intervention on the sources of greenhouse gas emissions. Climate change’s effects are already being felt around the globe in the form of coral bleaching, erratic and extreme precipitation and weather patterns, rising sea levels, arctic ice melt, and unprecedented record temperatures. If mitigation efforts are not implemented, it will impose epoch-making impacts geographically, environmentally,…

methane and oxygen levels. The replacement of these methods with electronic sensors has increased both the safety and reliability of gas detection. In addition, a wider variety of gases can be sensed and quantified. Despite these improvements, issues with sensors persist. Selectivity, the ability to differentiate between gases, proves a challenge, as do sensitivity to small gas concentration, repeat measurement stability, and cost. One possible way to compete with these challenges may be the…

Differences Between Gasoline and Diesel Many people just go to a gas station and fill up their car with the gas they need not knowing about what actually goes into the process of making the fuel and getting there. When people see diesel whose cars do not need it, their minds instantly think “Woops, that is diesel, better not use that kind of gas in my car or else something bad could happen.” Do people really know the differences between the two fuels? Could they explain to someone who wants to…

intensified use of fossil fuels and an increase rate of harmful gases such as carbon dioxide and nitrous oxide. Many scientists believe that climate change is occurring and they provide some scientific evidence to prove this, yet some people find it hard to believe that global warming actually exists. Global warming is defined as a gradual change in the overall temperature of the earth 's atmosphere caused by harmful greenhouse gases. Global warming is caused by carbon dioxide and other air…

source of energy is overdue. About 86% of the country’s types of energy sources originate from fossil fuel consumption and other closely linked greenhouse gases. Some of these emissions include carbon dioxide, methane and other harmful gases. Without an alternate source of energy the atmosphere will continue to trap higher amounts of toxic gases and eventually won’t be capable of providing enough oxygen for us to breathe. The Environment Protection Agency (EPA) has begun to produce new…
