PVT는 일정. 부피 계산. 23℃ 1.00 atm 1.00 L He balloon –31℃ 220. torr
A sealed balloon is filled with 1.00 L helium at 23℃ and 1.00 atm.
The balloon rises to a point in the atmosphere
where pressure is 220. torr and the temperature is –31℃.
What is the change in volume of the balloon
as it ascends from 1.00 atm to a pressure of 220. torr?
---------------------------------------------------
P1V1 / T1 = P2V2 / T2
( 참고 https://ywpop.tistory.com/7091 )
V2 = P1V1T2 / P2T1
= [(1.00) (1.00) (273.15 + (–31))] / [(220./760) (273.15 + 23)]
= 2.8246 L
답: 2.82 L
