Experiment Library
Perform the following experiments and more with the PASPORT Absolute Pressure Sensor.
Visit PASCO's Experiment Library to view more activities.
Ideal Gas Law
In this lab, students will use an absolute pressure sensor and stainless steel temperature sensor to determine the number of moles of carbon dioxide gas generated during a reaction between hydrochloric acid and sodium bicarbonate.
Boyle's Law
This lab uses the Ideal Gas Law Apparatus syringe to examine Boyle's Law. Using this apparatus, you will hold the temperature of a gas constant while changing the volume of the gas and measuring the volume and the absolute pressure.
Gay-Lussacs's Law and Absolute Zero
In this lab, students use an absolute pressure sensor and fast response temperature sensor to determine the temperature at which all motion stops (absolute zero).
Boyle's Law
In this lab, students will use absolute pressure sensors to investigate how changes in the volume of a confined gas with constant temperature affects pressure.
Rates of Reaction
In this lab, students will use an absolute pressure sensor to determine the effects of temperature, concentration, and surface area on the rate of a chemical reaction by measuring changes in absolute pressure as the reaction proceeds.
Absolute Zero
In this lab, students will use absolute pressure and temperature sensors to experimentally determine a numerical value for absolute zero in degrees Celsius.
Boyle's Law
In this lab, students use an absolute pressure sensor to determine volume's effect on the pressure of a closed system containing a fixed amount of molecules at a constant temperature.
Boyle's Law
In this lab, students will use absolute pressure sensors to observe the relationship between volume and pressure of an enclosed gas at constant temperature.
Absolute Zero
A constant-volume gas thermometer is used to determine the value of absolute zero in degrees Celsius by plotting Temperature vs. Absolute Pressure and finding the temperature at which the Absolute Pressure is zero.
Percent Oxygen in Air
In this lab, students use an absolute pressure sensor to study air characteristics and determine the percent of oxygen present.
Yeast Growth
In this lab, students will use a temperature sensor and an absolute pressure sensor to measure the changing pressure inside a flask of fermenting yeast cells at two different temperatures.
Boyle's Law
Rediscover Boyle's Law by holding the temperature of a gas constant and changing the volume of the gas, and measuring the volume and the absolute pressure.
