Dik : m1 = 50 g m2 = 100 g ΔT1 = 80'C ΔT2 = 80'C Dit : T cam ? Jwb : m1.c1.ΔT1 = m2.c2.ΔT2 50 g . (80'C - T cam) = 100 g . (T cam - 80'C) 4000 g'C - 50 g T cam = 100 g T cam - 8000 g'C 4000 g'C + 8000 g'c = 100 g T cam + 50 g T cam 12.000 g'C = 150 g T cam T cam = 12.000 'C / 150 = 80'C
(50.80)+(100.80)/50+100
4000+8000/150
12000/150
80
m2 = 100 g
ΔT1 = 80'C
ΔT2 = 80'C
Dit : T cam ?
Jwb :
m1.c1.ΔT1 = m2.c2.ΔT2
50 g . (80'C - T cam) = 100 g . (T cam - 80'C)
4000 g'C - 50 g T cam = 100 g T cam - 8000 g'C
4000 g'C + 8000 g'c = 100 g T cam + 50 g T cam
12.000 g'C = 150 g T cam
T cam = 12.000 'C / 150
= 80'C
maaf ya kalau salah
