Gas Pressure Sensor

The Gas Pressure Sensor can be used to monitor pressure changes in gas-law experiments.   Vapor pressure of various liquids and solutions can be monitored using this sensor.

Use the Gas Pressure Sensor to:
  • investigate the relationship between pressure and volume, Boyle's law
  • measure vapor pressure of liquids
  • study the effect of temperature on gas pressure, Gay-Lussac's law
  • monitor the production of O2 during photosynthesis of an aquatic plant in a closed system
  • determine the rate of transpiration for a plant under different conditions
  • determine the rate of respiration in germinating pea or bean seeds
  • monitor the pressure of a confined air pocket as water moves in and out of a semi-permeable membrane by osmosis
  • study the effect of temperature and concentration on the rate of decomposition of H2O2.
