  • Q1=M.C.ΔT1
    =30gram. 2100J/kg°c. (0-(-2))
    =30gram. 2100J/kg°c. 2°c
    =30gram. 4200J/kg
    30gram=0,003kg
    =0,003kg.4200j/kg
    =12,6j
    Q2=M.CL
    =30gram. 336000J/kg
    30gram=0,003kg.336000J/kg
    =1008J

    Q3=M.C.ΔT2
    =30gram. 2100J/kg°c. (0-5)
    =30gram. 2100J/kg°c. 5°c
    30gram =0,003kg.2100J/kg°c. 5°c
    =31,5J
    Q Total=12,6J+1008J+31,5J=1052,1 J
