Suhu dan KalorDiketahui:
m = 2 kg
∆t = 100-28 = 72°C
c = 4200 J/kg°C
P = 350 watt
Ditanya:
t = ?
Jawab:
Q = W
m · c · ∆t = P · t
2 · 4200 · 72 = 350 · t
604800 = 350t
604800 : 350 = t
t = 1728 sekon
t = 28 menit 48 sekon
Keterangan:
m = massa
∆t = perubahan suhu
c = kalor jenis
P = daya
W = usaha
t = waktu
*semoga membantu. sukses selalu ^_^
