This demonstration shows pressure vs. temperature in a gas at a fixed volume. The bulb is placed in different temperature liquids to observe the change in pressure.
* Equipment seen in the video may vary from equipment used in ND Demonstrations. See information and images below for ND equipment and setup.
Setup:
Place the constant volume bulb and beakers of fluids on the demo table.
With the valve on the apparatus closed, place the bulb in the different fluids and observe the pressure change.
Notes:
If temperature and pressure values are recorded, absolute zero can be determined.
