t1 = 10'C
t2 = 80'C
C es = 2100 j/kg'C
C air = 4200 J/kg'C
L es = 336.000 J/kg
Dit : Q ?
jwb :
Q1 = m.C es.T1
= 5 kg . 2100 J/kg'C . 10'C
= 105.000 J
Q3 = m.L es
= 5 kg . 336.000 J/kg
= 1.680.000 J
Q2 = m.C air.T2
= 5 kg . 4200 J/kg'C . 80'C
= 1.680.000 J
Q total = 1.680.000 + 1.680.000 + 105.000 = 3.465.000 J = 3.465 kJ
maaf ya kalau salah
