tolong dijawab soal ny besok dikumpul

Dik : m = 4 kg ; c.air = 4200J/kg°C ; c.es = 2100J/kg°C ; L.es = 340000J/kg ; ΔT = 10°C
Dit : Qa-b-c = ... ?
Jwb : Qa-b = m.c.ΔT
= 4 kg . 2100J/kg°C . 10°C = 84000 J
Qb-c = m . L.es
= 4 kg . 340000J/kg = 1360000 J
Qa-b-c = 84000 J + 1360000 J = 1444000J = 1444 kJ (c)
