1. In an experiment, a closed container holds a 10.0 g sample of an alcohol. The
container is cooled at a constant rate. The sample's temperature is recorded each
minute. A graph of the data is below. A phase diagram for the alcohol is also
shown.

Expert Solution
Step 1

In this question, we have a pressure vs temperature graph where Pressure is plotted on the Y-axis(dependent variable) and Temperature is plotted on the X-axis(independent variable). 

Regression equation for the straight line is given as:

y = 0.017x + 1.940
