Under Pressure: Faulty Pressure Cooker?
Experiment #13 from Forensic Chemistry Experiments
- Subject
- Chemistry
Introduction
Pressure cookers are typically used to reduce the time it takes to prepare a meal.
For safety reasons, you will measure the pressure change of the air in a fixed volume as it is subjected to various temperatures. This system will model what is happening in a pressure cooker.
You will plot a graph of pressure versus temperature and use the graph to evaluate the performance of the pressure cookers in question.
From your data you will determine the mathematical relationship between the pressure and temperature of a fixed volume of gas.
Objectives
- Conduct an experiment to determine the relationship between pressure and temperature for a fixed volume of gas.
- Use the investigator’s report along with your data to decide if the pressure cookers in question were functioning properly.
Sensors and Equipment
This experiment features the following sensors and equipment. Additional equipment may be required.
