Tolong sama caranya ya!!!

Answer 1

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
