Q = 400 Joule
m = 500 gr = 0.5 kg
Perbedaan Suhu (Delta t) = 75-40 = 30 derajat
-----
ditanya = c ( kapasitas kalor )
-----
jawab
Q = m.c.delta t
400 = 0.5 . c . 30
400 = 150 . c
c = 400 / 150
c = 2 100/150
c = 2 2/3
kapasitasnya 40 joule kah...???
H = m*c
H = 0.5 * 8/3
H = 5/10 * 8/3
H = 40 / 30
H = 4 / 3
