Question

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

Depth of Water and Water Pressure
A graph entitled Depth of Water and water pressure has depth on the x-axis and pressure on the y-axis. A line with positive slope goes through (0, 1) and (32, 2).
Based on the information in the graph, what is the water pressure at sea level?
StartFraction 1 Over 32 EndFraction atm
One-fourth atm
0 atm
1 atm

Answer 1

1 atm

The graph shows the point (0, 1), meaning at depth 0 ft (sea level) the pressure is 1 atmosphere.
