Question

Tolong bantuin dong, aku bingung. Kalau bisa pake caranya yh

Answer 1

Diketahui =
m = 1 kg
T₁ = 300°C
c = 900 J/kg°C
Q = 45 kJ
    = 45000 J

ditanya =
T₂ = ...

dijawab =
ΔT = Q / (m . c)
      = 45000 J / (1 kg . 900 J/kg°C)
      = 45000 J / 900 J/°C
      = 50°C

ΔT = T₂ - T₁
T₂ = ΔT + T₁
     = 50°C + 300°C
     = 350°C
