Use Excel, or similar, to make a graph of pressure vs depth. Do a linear best fit and include the equation on the graph. Copy and paste your graph and equation below.

What is the physical meaning of the slope?What is the physical meaning of the y-intercept?

Now, pick a depth and vary the fluid density from 700 to 1,400 kg/m³. Record your results on the table below. Note that the simulation will give you kPa. Convert to Pa before entering the values on the table.

What is the physical meaning of the y-intercept?

How would your two graphs differ if you gathered data from Mars? Jupiter? Explain why. Try to come up with the answer before testing it.

Based on what you learned in this activity, what is the formula for determining the pressure in a fluid? State what each of the symbols mean.
