PV/T는 일정. A scuba diver 40 ft below the ocean surface inhales 85.0 mL

결합된 기체 법칙. combined gas law

 

 

A scuba diver 40 ft below the ocean surface inhales 85.0 mL of compressed air from a scuba tank at a pressure of 2.80 atm and a temperature of 7.

What is the pressure of the air, in atm, in the lungs when the gas expands to 185.0 mL at a body temperature of 37, and the amount of gas remains constant?

 

---------------------------------------------------

 

PV / T = P’V’ / T’

( 식 설명 https://ywpop.tistory.com/7091 )

 

PVT’ = P’V’T

 

P’ = PVT’ / V’T

= [(2.80) (85.0) (273+37)] / [(185.0) (273+7)]

= 1.42 atm

 

 

: 1.42 atm
