soal ipa bagian kalor

Diketahui :
Mp = 400 g = 0,4 kg, delta Qp= 14 kj = 14000 j
Mq = 500 g = 0,5 kg, delta Qq= 20 kj = 20000 j
Mr = 800 g = 0,8 kg, delta Qr= 12 kj = 12000 j
Ms = 1200 g = 1,2 kg, delta Qs= 48 kj = 48000 j

C = Q/m.delta T

CP = Qp/mp.delta Tp
CP = 14000/0,4.50
CP = 700 J/kgºC

CQ = Qq/mq.delta Tq
CQ = 20000/ 0,5.40
CQ = 1000 J/kgºC

CR = Qr/mr.delta Tr
CR = 12000/0,8.60
CR = 250 J/kgºC

CS = Qs/ms. delta Ts
CS = 48000/1,2.100
CS = 400 J/kgºC

Jadi, zat cair yang terbesar ke terkecil adalah : Q,P,S,R.
