Question
Does an increase in greenhouse gas concentration result in higher atmospheric temperatures?
Materials
3 350ml flask
air line tubing
bucket of water
Alka-Seltzer
lamp
2 temperature probes
rubber stoppers
Methods
We filled one flask with CO2 using the gas from dissolved Alka-Seltzer, and a second flask with atmospheric air. A temperature probe was placed in each flask, and both flasks were placed in front of a bright lamp.
detailed description of methods used
Hypothesis
The Temperature will be higher inside the flask enriched with CO2 than in the flask containing air.
Results
The flask with CO2 started off cooler than the flask with air. After 10 minutes the temperature inside the flask with CO2 was higher than inside flask with air.
Conclusions
CO2 is a greenhouse gas and increases in green house gases can cause global warming.
