1. The data table below provides the changes in pressure for a gas in a close system as the temperature of the gas is increased. Plot these data and draw a trend line that goes through the data. You may use the graph provided below, or you may use graphing paper or an online graphing program to plot your data and upload the document as a separate file.

• Calculate the slope of the trend line including the units. Be sure to show all steps of your calculations.

• How are the variables of temperature and pressure related to one another?

• Use the trend line to determine what will be the gas pressure at 0°C.
