Question

Please jawab no. 5, mohon bantuanya

Answer 1

Yang ditanya suhu akhir( Ta ) perbandingan rumusnya ---> m besi x c besi x delta Tbesi  =  m air x c air x delta Tair

* delta Tbesi = Ta - Tbesi
* delta Tair = T1 - Ta

Answer 2

Qbes=Qair
m.c.∆T=m.c.∆T
0,5.450.(45-X)=0,5.4200(X-25)
20250-450X=4200X-105000
4650X=125250
X=27°C
