Ascuba diver at the surface of the sea takes a deep breath and fills her lungs with 6 liters of air. the pressure in her lungs is 1 atm. she then dives down ten meters, without inhaling or exhaling, until the pressure of the air in her lungs is 2 atm. according to boyle’s law, what happens to the air in her lungs as she dives down? a. the temperature increases. b. the volume increases. c. the volume decreases. d. the temperature decreases.

Steam reforming of methane ( ch4) produces "synthesis gas," a mixture of carbon monoxide gas and hydrogen gas, which is the starting point for many important industrial chemical syntheses. an industrial chemist studying this reaction fills a 1.5 l flask with 3.5 atm of methane gas and 1.3 atm of water vapor at 43.0°c. he then raises the temperature, and when the mixture has come to equilibrium measures the partial pressure of carbon monoxide gas to be 1 .0 atm. calculate the pressure equilibrium constant for the steam reforming of methane at the final temperature of the mixture. round your answer to 2 significant digits.
