Alumunium bermassa 2 kg dgn suhu 20 derajat Celcius menerima kalor sebesar 180 kJ. Jika kalor jenis alumunium=900 j/kg derajat celcius, suhu akhir alumunium adalah…

120 derajat *maaf kalau salah*

M = 2 kg
t1 = 20 °C
Q = 280 kJ = 280000 J
c = 900 J/kg°C
t2 = … °C
mcΔt = Q
2 x 900 x (t2 – 20) = 280000
1800 x (t2 – 20) = 280000
t2 – 20 = 280000 / 1800
t2 – 20 = 155,6
t2 = 175,6
