Jawab:
1.Diketahui :
m = 2 kg
Q = 7 × J = 700.000 J
ΔT = 100°C – 30°C = 70°C
Ditanyakan : c. . . ?
Jawab :
c = Q / m T
c = 700.000 J / (2 kg) (70°C)
c = 700.000 J / 140 kg°C
c = 5000 J/kg°C
c = 5000 J/kg K
2.Dik : m = 4 kg
t1 = 60'C
Q = 39.000 J
C = 390 J/kg'C
Dit : t2 ?
Jwb :
Δt = Q / m.c
(t2 - t1) = Q / m.c
(t2 - 60) = 39.000 / 4.390
(t2 - 60'C) = 25'C
t2 = 25'C + 60'C = 85'C
maaf ya kalau salah
