Question 40
Easy

A student measures the total pressure at different depths in a column of sugar solution. Their results are plotted on the graph in Figure 1.

Figure 1: A line graph titled 'Total Pressure vs. Depth'. The y-axis is labeled 'Total pressure in kPa' and ranges from 100.0 to 107.0 in increments of 1.0. The x-axis is labeled 'Depth in cm' and ranges from 0 to 50 in increments of 10. Four data points are plotted with crosses at (10, 102.2), (20, 103.4), (30, 104.6), and (40, 105.8). A straight line of best fit is drawn through the points and is extrapolated back to cross the y-axis at depth = 0 cm.

Use the graph in Figure 1 to predict the pressure at the surface of the sugar solution.
