Snorkelers breathe through short tubular "snorkels"
while swimming under water very near the surface.
One end of the snorkel attaches to the snorkeler's
mouth while the other end protrudes above the
water's surface. Unfortunately, snorkels cannot
support breathing to any great depth: it is said that
a typical snorkeler below a water depth of only
about 30 cm cannot draw a breath through a
snorkel.
Part A
Based on this claim, what is the approximate fractional change in a typical person's lung volume when drawing a breath?
Assume,
in equilibrium, the air pressure in a snorkeler's lungs matches that of the surrounding water pressure.
Express your answer using two significant figures.

Scuba divers are warned that if they must make a rapid ascent, they should exhale on the way up. If a diver rapidly ascends to the surface with lungs full of air, his lungs could be damaged. Explain why this is so.
You fill a balloon with helium and let it go. It floats up into the air, where it is essentially floating in a pool of air. Why does the helium filled balloon float in air? Make sure you use the words ‘buoyancy’, ‘density’ and ‘volume of displaced ‘air’ in answering this question.

- Consider the piston cylinder apparatus shown in Figure P20.81. The bottom of the cylinder contains 2.00 kg of water at just under 100.0c. The cylinder has a radius of r = 7.50 cm. The piston of mass m = 3.00 kg sits on the surface of the water. An electric heater in the cylinder base transfers energy into the water at a rate of 100 W. Assume the cylinder is much taller than shown in the figure, so we dont need to be concerned about the piston reaching the top of the cylinder.

(b) After the water has completely turned to steam and the heater continues to transfer energy to the steam at the same rate, how fast is the piston rising?arrow_forwardA vertical cylinder of cross-sectional area A is fitted with a tight-fitting, frictionless piston of mass m (Fig. P18.40).

This pressure produces a flow of 20.0 L/min through a garden hose.
