Do Higher Carbon Dioxide Levels Lead to Warmer Conditions?

Extracts from this document...

Introduction

7/01/04 Do Higher Carbon Dioxide Levels Lead to Warmer Conditions? Analysis From the graph, one can clearly see a pattern between the air and carbon dioxide. Both rise steadily until 20 minutes and then when the lamp is turned off, they both decline. After the first 10 minutes the temperature of the air is 21.90�C and the temperature of the carbon dioxide is 22.40�C, so there is a difference of 0.50�C. After 20 minutes the temperature of the air is 22.70�C and the temperature is 23.30�C, and there is a difference of 0.60�C. This shows that the carbon dioxide has increased by 0.10�C. After 30 minutes the temperature of the air was 21.70�C and the temperature of the carbon dioxide was 21.90�C. So you can see already, that after 10 minutes of the light being switched off, that the temperature gap between the air and carbon dioxide is getting smaller already. ...read more.

Middle

From the graph you can see that carbon dioxide maintains temperature better than air. When heated, it heats quicker than air and when the heat is stopped it retains the heat better than air. This shows that carbon dioxide is a main contributory gas of the greenhouse effect. If carbon dioxide absorbs and retains heat energy then the energy which heats the earth and is reflected off, will be retained. Evaluation The reliability of the experiment is not very good when considering all the factors. As the experiment was not repeated, there is only one set of results. This is not accurate and this experiment could have been an anomaly, we do not know however, as we only have these results. If we had more than one, we could find an average which would smooth out any anomalies. ...read more.

Conclusion

If it was closer to the bottle containing air then this would have also have affected the results. As we were using two lamps they could have had different voltages and be providing more heat to one than to another, thus affecting the results. All in all the experiment was not that reliable. This could have been improved by repeating the experiment several times to get lots of results. Then an average can be gained which would show more accurately if carbon dioxide levels lead to warmer conditions. From the results gained, it looks like carbon dioxide levels do lead to warmer conditions. Carbon dioxide warms quicker than air and stays warmer for longer. This is why rising carbon dioxide levels in the air are worrying. If more heat is trapped in the atmosphere then the earth will get warmer leading to the extinction of many animals and the loss of many habitats. ?? ?? ?? ??

    The main toxic effect of high concentrations of lead on a plant is the effect on plant growth. Lead will stop plant growth because lead acts as a non-competitive irreversible enzyme inhibitor. Enzymes are required for many metabolic reactions such as respiration and photosynthesis.
