The Temperature-Pressure Relationship. Type. Virtual Lab Explore the relationship between the temperature of a gas and the pressure it exerts on its. Prepare the Temperature Probe and Gas Pressure Sensor for data collection. . The complete Chemistry with Vernier lab manual includes 36 labs and essential . It is predicted that pressure will have a direct relationship with temperature because an increase in temperature causes particles to.

A graph of pressure vs. The apparatus consists of a copper bulb having a fixed volume copper expands and contracts only slightly with temperaturea pressure gauge, and a fixed mass of gas. Gas pressure is measured with the pressure gauge.

Before a measurement is taken, the apparatus is allowed to equilibrate to ensure that the gas and bulb are at the same temperature.

Do not use open flames during the experiment.

Ethanol and acetone are very flammable. Dry ice and liquid nitrogen should be handled very carefully wear safety glasses and insulated thermal gloves due to the risk of frostbite.

Never put dry ice or liquid nitrogen in a closed container because each will build up pressure and explode the container. Wear safety glasses during the experiment. Use insulated thermal gloves and appropriate care when handling the water baths, dry ice, liquid nitrogen, and Absolute Zero Demonstrator. Procedure All participants put on safety glasses. Individuals responsible for handling the Absolute Zero Demonstrator apparatus, water baths, dry ice, and liquid nitrogen put on insulated thermal gloves.

Support the apparatus with a large 3-prong clamp and clamp holder and support the thermometer with a small 3-prong clamp and clamp holder. Allow the water to return to a full boil. Wait a few minutes for the apparatus to equilibrate.

The pressure reading should stabilize at a constant value. Record the pressure to the nearest mm Hg and temperature to the nearest 0. Remove the apparatus from the bath. Support the apparatus and thermometer as described in step 2. Repeat steps 3 to 5. Twist the stopper into the neck of the flask to ensure a tight fit.

Attach the connector at the free end of the plastic tubing to the pressure sensor valve with a clockwise turn see Figure 4.

Then close the 2-way valve above the rubber stopper by turning the valve handle so it is perpendicular with the valve stem itself. The air sample to be studied is now confined in the flask.

Turn on the CBL unit and the calculator. Set up the calculator and CBL for data collection. Make sure the entire flask is covered see Figure 4. Repeat the Step 10 procedure using the room-temperature bath. Repeat the Step 10 procedure using the hot-water bath.

Remove the boiling water from the hot plate. Do not burn yourself or the probe wires with the hot plate. To keep from burning your hand, hold the tubing of the flask using a glove or a cloth.

After the temperature probe has been in the boiling water for a few seconds, place the flask into the boiling-water bath and repeat Step Examine the data points along the displayed graph of pressure vs. As you move the cursor right or left, the temperature X and pressure Y values of each data point are displayed below the graph. Record the data pairs in your data table. Round pressure to the nearest 0. Examine your graph of pressure vs.
