Penjelasan:
Dik :
m = 800 gram = 0,8 kg
∆T = 120 - 40 = 80°C
Q = 64.000 J
Dit : Kalor jenis (c)
Jawab :
Q = m·c·∆T
64.000 = 0,8·c·80
64.000 = 64c
c = 64.000/64
c = 1.000 J/kg°C
Q = (M(C(∆T)
64.000 = (800/1.000)(C)(120 - 40)
64.000 = (0,8(C(80)
64.000 = (0,8(80(C)
64.000 = 64C
64C = 64.000
(64 ÷ 64)C = 64.000 ÷ 64
C = 1.000 J/KG°C
