Experiment to Demonstrate the Greenhouse Effect.
2 conical flasks are placed on an overhead projector and left to come to a stable temperature. This temperature is recorded.
Carbon dioxide is generated through a reaction of calcium carbonate and 2 molar hydrochloric acid. One of the conical flasks is supplied with this carbon dioxide creating a CO2 rich atmosphere. The other flask is left unchanged.
After 10 minutes the temperature is recorded again.
The temperature of the flask with a carbon dioxide atmosphere was found to increase by 4.5 deg C whereas the temperature of the flask with a normal atmosphere remained unchanged
