Model the behavior of atmospheric gases

The Atmospheric Properties Chamber is designed to help students model gas behavior in the atmosphere.  Using the Atmospheric Properties chamber, students can recreate and quantify the characteristics present when a cloud forms.  

To use the apparatus students add a small amount of water to the reservoir at the bottom of the chamber.  Then seal the chamber with the included thumbscrews, and press the rubber stopper into place on the top of the chamber.  To make the cloud, students add pressure to the chamber using the included syringe.  When the pressure is high enough, the rubber stopper with ‘blow’ out and a cloud will form.

Take the gas laws one step further and give PV=nRT new meaning as your students quantitatively explore and visualize the effect of changing pressure and temperature.  Using a pressure sensor such as the Chemistry sensor (PS-2170 - not included) along with the built-in, ultra fast temperature sensor allow students to quantitatively measure both variables simultaneously.  You can see how the pressure and temperature change with each pump of the syringe.  

This versatile chamber is perfect for modeling low pressure experiments too.  Your students can make water boil by evacuating air from the chamber – best of all they can see what temperature and pressure at which it boils.

The Atmospheric Properties Chamber also includes 2 ball-valve stopcocks so that samples of gasses may be easily added or removed and the chamber resealed in order to monitor the effects of those changes.
