Kesalahan. Air bermassa 500 gram dipanaskan dari suhu 10° hubgga mendidih (100°). Jika kalor jenis air 4200 J/kg °C, tentulan banyaknya kalor yg diserap!
Zuhh
Dik : m = 500 gram = 0,5 kg T0 = 10 C T = 100 C c = 4.200 J/KgC dit : Q ?
dijwb : Q = m x c x ΔT = 0,5 x 4.200 x (100-10) = 0,5 x 4,200 x 90 = 189.000 J

500 g = 0,5 kg = 0,5 kg × 4200 j/kg°c × ( 100°c - 10°c) =0,5 kg × 4200 j/kg°c × 90°c =189.000 J
m = 500 gram = 0,5 kg
T0 = 10 C
T = 100 C
c = 4.200 J/KgC
dit : Q ?
dijwb :
Q = m x c x ΔT
= 0,5 x 4.200 x (100-10)
= 0,5 x 4,200 x 90
= 189.000 J
= 0,5 kg × 4200 j/kg°c × ( 100°c - 10°c)
=0,5 kg × 4200 j/kg°c × 90°c
=189.000 J
