PVT는 일정. 106.0 L 45.0℃ 740.0 mmHg 20.0℃ 780.0 mmHg

 

 

A gas balloon has a volume of 106.0 liters

when the temperature is 45.0℃ and the pressure is 740.0 mmHg.

What will its volume be at 20.0℃ and 780.0 mmHg pressure?

P1V1 / T1 = P2V2 / T2

( 참고 https://ywpop.tistory.com/7091 )

 

 

 

V2 = P1V1T2 / T1P2

= [(740.0) (106.0) (273.15+20.0)] / [(273.15+45.0) (780.0)]

= 92.66 L

 

 

 

답: 92.7 L
