The Greаt Bаrrier Reef neаr Australia is repоrted tо have the best diving in the wоrld. Along the Reef, a scuba diver goes down 50 ft to look at the sea creatures. As she descends, the air pressure increases, but this is regulated by continuous breathing. Identify the applicable gas law if the diver held her breath.
