Featured in PASCO’s Chemistry through Inquiry Teacher Guide
Features over 25 inquiry based labs covering the fundamental concepts of lab skills, structure & properties of matter, chemical reactions and more.
Use an absolute pressure sensor and fast response temperature sensor to determine the temperature at which all motion stops (absolute zero).
Determine the temperature at which all motion stops. Through this investigation, students:
- Show that a directly proportional relationship exists between pressure and temperature for a gas at constant volume.
- Relate the Kelvin temperature scale to the motion of molecules.
- Show that Gay-Lussac’s law, P/T = k and P1/T1 = Pz/Tz is valid only with Kelvin temperatures.
Students conduct the following procedures:
- Use an absolute pressure sensor to determine the pressure of a fixed volume of air at various temperatures.
- Record collected temperature data in both Celsius and Kelvin units.
- Graph pressure versus temperature data showing the line of best fit (linear regression).
- Use the equation for the line of best fit to determine absolute zero.
