Question

Figure 3 shows a scuba diver ascending from 20 m below the surface where the water temperature is 10 °C, to the surface, where the temperature is 25 °C and the pressure is 1.01 x 10 Pa.

Calculate the pressure the diver is subjected to at 20 m below the surface of the water.

[Density of water = 1025 kg m-³]

[Acceleration due to gravity, g = 10 m s]​
