Experiment No ____ 2.0 hours D1=2,D2=1,D3=0 The Effect of Temperature on the Solubility of Carbon Dioxide in Water under Constant Pressure Beijing World Youth Academy Subject: Chemistry Student name: YeiYoung Choo Candidate number: 000791 011 January 21, 2009 Teacher Helen Xu The Effect of Temperature on the Solubility of Carbon Dioxide in Water under Constant Pressure (Evaluated for Design) Research Question What is the effect of temperature on…

Background Information Alcohols are a class of organic compounds characterised by one or more hydroxyl (-OH) groups attached to a carbon atom of a hydrocarbon chain. They can be considered as organic derivatives of water and in which a hydrogen atom has been replaced by an alkyl group. Alcohols are a common form of organic compound and most are colourless liquids or solids at room temperature (Encyclopaedia Britannica, 2015). Combustion is the process of burning fuels or in this case alcohol.…

1. A Carbon dioxide (CO2) absorbs energy from the sun, then releases it back into earth; it is the second largest greenhouse gas after water vapour. Carbon dioxide releases out a harmful gas, which is dissolved out to the atmosphere determined by temperature. However CO2 is not one of the main impulsive forces in causing climate shifts, but as the climate cools the concentration of CO2 decreases this then has a further cooling effect. Causing this irregular rise and fall in CO2 levels is the shift…

Water Properties and pH Abstract: These set of experiment are set up to observe water properties and pH in both base and acidic solution. The first 7 are testing the properties of water and its function to support life. The last 3 are experimenting the pH of different solution as well as the use of buffer in nature and medical. Some experiments is omitted or change due to error in preparation, but overall the experiment does show significant details for natural phenomenal. Introduction: the purpose…

Without carbon dioxide plants cannot photosynthesize. Through reading various books and web pages it was made clear that carbon dioxide is definitely one of the raw materials needed for photosynthesis, but I wanted to see whether this is actually true and if carbon dioxide is taken away completely will the plant photosynthesize at all? By taking a two plants of the exact same species, de-starching them both followed by putting plant one in conditions where carbon dioxide is taken away completely…

1996), we can find an interesting point--the lifetime of carbon dioxide is ??variable??, which can be as long as a century time-scale. Because of this feature, even if human beings stop emitting CO2 to the atmosphere from now on, it will still take a long time for the earth to remove the extra carbon dioxide from the atmosphere, so the atmospheric temperature will keep going up for a long time. Therefore, the residence time of carbon dioxide is broadly applied in analysing the future warming risks…

Carbon dioxide represents 84% of greenhouse gases. It is not only affecting the atmosphere but also the oceans in that it has made them 30% more acidic in turn affecting sea organisms. As you can see these fossil fuels create a chain effect damaging more than we are aware of. One of the biggest problems with switching to renewable energy isn’t that we couldn’t make it work or the startup cost is too much, it’s because, as most people agree, the oil businesses doesn’t want to lose out on the money…

The presence or absence of light in cyanobacterial species in Inland Sea, Qatar: effects on carbon dioxide flux rate Maryam Own BIOG 14th of March 2013 Abstract The Inland Sea in Qatar contains colonies of microorganisms living in both vertical and horizontal zonation. Cyanobacteria live on the horizontal upper-intertidal layer of the soil. Cyanobacteria is known for existing for more than 3.5 billion years, and has therefore adapted to live in many conditions (in the cold Arctic…

each year, of all the carbon dioxide that human activity emits into the air. Scientists originally believed that the idea of our oceans absorbing extra carbon dioxide that is in the air was a positive idea, because it would deter global warming. But, they soon came to the realization that this absorption process was having similarly disastrous effects, as global warming does, and it what happening to our oceans. This phenomenon, of our oceans taking in the excess carbon dioxide from the atmosphere…

It is a recorded fact that the amount of carbon dioxide in the atmosphere today is at the highest level ever recorded or studied. The large number of invasive carbon dioxide molecules is causing detrimental problems in the environment. This gas is linked to the Earth’s drastically rising temperatures, causing the rising sea level and thousands of arctic animals to lose their homes. This is an unignorable problem that needs great minds who are passionate and determined in this field. The most substantial…
