Hg 366 g 77.0℃ 12.0℃ kJ
Calculate the amount of heat liberated (in kJ)
from 366 g of mercury when it cools from 77.0℃ to 12.0℃.
---------------------------------------------------
> 수은의 비열 = 0.139 J/g•℃
q = C m Δt
( 참고 https://ywpop.tistory.com/2897 )
= (0.139 J/g•℃) (366 g) (12.0 – 77.0 ℃)
= (0.139) (366) (12.0 – 77.0)
= –3306.8 J
답: –3.31 kJ
