2kg 10°c sampai 50°c 42.000j maka kajor jenis sat tersebut

Q = m.c.delta T
42000 J = 2 kg . c . (50-10 c)
42000 J = 2 kg . c . 40 c
42000 J = 80 kg.c
42000/80 = c
5,25 J/kgC =c

Semoga membantu dan semoga bermanfaat...

m = 2 kg
T1 = 10°C
T2 = 50°C
∆T = (T2 - T1) = 50 - 10 = 40°C
Q = 42.000 j = 42 kj

Ditanya c??

Jawaban
Q = m x c x ∆T
42 = 2 x c x 40
42 = 80 x c
42/80 = c
0,525 = c

Kalor jenis nya = 0,525 x 1000 = 525 J/Kg °C
