Question

The amount of water pressure exerted on a scuba diver varies with depth.The graph below shows the relationship between pressure, p, in atms, and depth, d, in ft.

Depth of Water and Water Pressure

Based on the information in the graph, what is the water pressure at sea level?

Answer 1

1 atm

Explanation:

Answer 2

The water pressure at the sea level is 1 atm.

Explanation:

Please find the attached graph of the relationship between pressure, p, in atms, and depth, d, in ft.

Upon looking at out given graph, we can see that pressure p (in atms) is represented on y-axis, and depth, d (in ft) is represented on x-axis.

Since d represents depth, so at the sea level depth will be 0 feet.

Now let us see our graph to find the value of y at x equals 0 or we need to find the y-intercept.

We can see that when x equals 0, the value of y is 1. Therefore, the water pressure at sea level is 1 atm.
