Use a fast response temperature sensor and an EcoChamber to determine the effect of a man-made organofluorine compound, a greenhouse gas, on the trapping of heat in an isolated system.
Determine the effect of a man-made organofluorine compound, a greenhouse gas, on the trapping of heat in an isolated system. During this investigation, students:
- Reproduce and study a greenhouse gas environment.
- Describe the relationship between the type of gas in a system and its ability to absorb energy.
- Consider the impact of human-made solutions to global warming and ozone-depletion.
Students gain experience conducting the following procedure:
- Simulating a greenhouse gas environment using difluoroethane
Sensors / Equipment Used:
MultiMeasure sensor that incorporates pH, conductivity, temperature, and the optical dissolved oxygen probe.
A single polycarbonate chamber designed to integrate sensors for controlled-environment experiments such as fermentation and plant or cricket respiration.
