Dik : m = 0,5 kg = 500 g T1 = -10 °C T2 = 0 °C Ces = 0,5 kal/g°C L = 80 kal/g°C Dit : Qab dan Qbc Jwb : Qab = mCesΔT = 500(0,5)(10) = 2500 kal Qbc = mL = 500(80) = 40.000 kal
=500.0,5.(0-(-10)
=250.10
=2500 kalori
BC = m.l
500.80
= 40.000 kalori
T1 = -10 °C
T2 = 0 °C
Ces = 0,5 kal/g°C
L = 80 kal/g°C
Dit : Qab dan Qbc
Jwb : Qab = mCesΔT
= 500(0,5)(10)
= 2500 kal
Qbc = mL
= 500(80)
= 40.000 kal
Jawabannya D. 2500 kal dan 40.000 kal
