The Effect of Temperature on Carbon Dioxide Levels
Background
Global warming is arguably the most daunting problem society faces today.
Research has shown that increased carbon dioxide levels is increasing the temperature of
Earth (Hansen, 2010). However, perhaps, the relationship is reversed; what if it is the increased temperature of Earth that is catalyzing the higher carbon dioxide levels? What if, in turn, the higher carbon dioxide level is increasing the temperature? Perhaps the Earth is trapped in a positive feedback loop, where the higher temperatures lead to higher carbon dioxide levels, which then raise the temperature.
This experiment explores this concept of temperature’s effect on carbon …show more content…

The Earth’s greenhouse effect dictates that “the planet's temperature ultimately depends on the atmospheric level of carbon dioxide.” In effect, studies have found that the carbon dioxide level serves as a “thermostat” for Earth as it determines the temperature of the planet (Hansen, 2010). However, the close relationship between temperature and carbon dioxide levels over the last 800,000 years may also assert that temperature affects carbon dioxide, not only the other way around (Anderson, 2010). The underlying concept behind this experiment is that colder liquids hold more dissolved gases, and therefore carbon dioxide, than warmer liquids (Anderson, 2010). This experiment applies this concept using carbonated soda of various temperatures and their respective carbon dioxide levels.
Purpose
The purpose of this lab was to determine the effect of temperature on carbon dioxide levels in terms of carbon emissions from soda cans. Thus, the independent variable is the temperature of the soda, and the dependent variable measured is the carbon dioxide level as the soda can is opened.
Hypothesis
The relationship between the temperature of the soda and the amount of

Stoichiometry Lab Report

680 Words | 3 Pages

In the lab, the theoretical yield of CO2 was calculated by using the mass of the Alka-Seltzer (in Part A) and the mass of the anti-acid (Part B) were multiplied by the mole ratios that were involved in the reaction equation for each reaction and they were also divided by the molar mass of each substance. From the balanced chemical equations that were included in the calculation portion, the limiting reactant in part A was determined to be citric acid. The limiting reactant in part B was determined to be HCl because in the reaction, the HCl would ran out before the calcium carbonate. The stoichiometry would not have been different when converting between the different states of matter because the state is a measure of kinetic energy, and not

The probable effect of the increasing global atmospheric carbon dioxide concentration of agricultural yields was evaluated. A very accurate method for the determination for carbon dioxide and oxygen in our blood is described. The method depends upon the equilibration of a bubble of gas with blood at thirty seven degrees celsius (ninety eight point six fahrenheit ) and the analysis of the bubble for carbon dioxide and oxygen. The Roughton-scholander syringe is used both as the equilibration chamber and the bubble analysis, that means eliminating the necessity for transfer of the bubble. At sea-level, the accuracy of the technique by comparing the results with those of a tonometer technique.

Respiration In Crickets Lab Report

1667 Words | 7 Pages

Using a laboratory incubator, the crickets were warmed up in a bottle fifteen degrees warmer than their natural environment of twenty degrees celsius for five minutes. After the CO2 sensor was connected to the computer, it could measure the CO2 levels in the air. For the sensor to measure just the crickets CO2 emissions, it completely covered the opening of the cricket’s bottle enough for it to be airtight. Using Logger Pro, the data was transmitted onto the computer into a line graph with the exact data points, clearly displaying each test. The same was done with the colder temperature, being kept in an environment of fifteen degrees cooler than the cricket’s natural environment for five minutes.

As scientist try to hide their information in regards to humanly effects on the climate and environment, certain studies show the impacts of humans on the climate. One of the leading causes for global warming, or the rising temperature of the Earth’s climate, are greenhouse effects by humans. “According to nature international journal of science, Data compiled by Le Quéré and other members of the Global Carbon Project suggest that humans contributed around 10.4 billion tones of carbon into the atmosphere in 2011” (Monastersky). Only a small portion of this carbon is filtered through carbon sinks, such as the ocean and plants.

Greenhouse gases such as water vapour, carbon dioxide, methane, nitrous oxide and ozone, play a pivotal role in the absorption of heat emitted from the planet’s surface and lower atmosphere and thereafter causing the energy to radiate back towards the surface. The natural greenhouse effect is important as without it the global average temperature would be approximately 60 degree Fahrenheit colder. Unfortunately, increasing anthropogenic activities have resulted in substantial amounts of greenhouse gases subsequently intensifying the strength of the greenhouse effect. The outcome of doing so are alterations to the planet’s

Relationship Between Independent And Carbon Dioxide Levels In Graph

736 Words | 3 Pages

In Graph 3, the independent and dependent variables are the years (independent) and the carbon dioxide levels in ppm (dependent). This data clearly shows a direct relationship; when the years increase, the amount of carbon dioxide levels increase as well. Unlike the previous two graphs, there is a clear direct relationship between the years and the carbon dioxide levels in ppm. A reasonable explanation for this direct relationship is that in 1959 (where the graph started), greenhouse gas emissions really started to spiral, and this caused the increase in CO2 amounts in ppm. Because more greenhouse gases were emitted, the steady greenhouse effect was disturbed and this resulted in more sunlight being trapped and made into heat instead of getting

Ocean Acidification Essay

861 Words | 4 Pages

Ever since the industrial revolution commenced, around one third of the carbon dioxide released by human interference has been absorbed by the ocean, which is one of the reasons of the drastic change in climate as well. Without the ocean absorbing carbon dioxide, the carbon dioxide n the atmosphere would be drastically higher, with possibly increasing the levels of climate change. The point of the research is to see how will the pH affect the organisms in the marine ecosystem and does carbonation affect an organism’s mass and form. Many organisms that are part of the marine food chain are going to be affected by ocean acidification due the levels of acidity deteriorating the calcium carbonate within the animal. It turns out

Phenol-Sulfuric Acid Analysis Essay

A significant portion of the monosaccharides in soda are fructose, and, therefore, an assumption regarding the correlation that a standard curve generated from a glucose solution has with an unknown soda sample should not be made. It would be more appropriate to use a solution with approximately 1:1 ratios of fructose and glucose when constructing a standard curve for the phenol-sulfuric acid analysis of soda. This is approximately the ratio that is witnessed in commercial HFCS; therefore, it would create a standard curve that correlates more robustly with the soda

Climate Change And Synthesis Essay

430 Words | 2 Pages

Arguably the most significant thing humans have done to cause climate change is the drastic increase in CO2. As a result of human activities, carbon dioxide, methane, nitrous oxide, and the halocarbons (a group of gases containing fluorine, chlorine, and bromine) build up in the atmosphere over time, as well as the natural sources of CO2, like vegetation. The concentration ofCO2 has went from 280 to more than 380 parts per million in just two hundred years. Still currently rising, the burning of fossil fuels by humans will continue to cause global warming and climate
