When a diver is more than a few meters beneath the surface the air pressure in the lungs is?
When a diver is more than a few meters beneath the surface, the air pressure in the lungs is greater than the air pressure at the water's surface. As the diver ascends to the surface, the volume of air in the lungs would expand as the external pressure decreased.

As a general guide: ideal blood pressure is considered to be between 90/60mmHg and 120/80mmHg. high blood pressure is considered to be 140/90mmHg or higher. low blood pressure is considered to be 90/60mmHg or lower.
What is the correct equation for Boyle’s Law?
pv = k This empirical relation, formulated by the physicist Robert Boyle in 1662, states that the pressure (p) of a given quantity of gas varies inversely with its volume (v) at constant temperature; i.e., in equation form, pv = k, a constant.
What is the pressure above atmospheric pressure at a depth of 10.0 m below the surface of the ocean?
