Answer 2

6. Q = m × c × delta t
21000 = 5 × 4200 × delta t
delta t(kenaikan suhu) 21000/21000 = 1

7. Kenaikan suhu (delta t) = 30 - 14 = 16 derajat C
Q = m.c.delta t
7200 = 1 × c × 16
c = 7200 / 16 = 450 J/KgC

8. Q = m × l
Q = 0,3 kg × 336000 = 10080
massanya jadiin kg dulu biar sama satuannga dgn kalor jenisnya.
