= 1×2100×5
= 5×2100
= 10500J
=10,5 KJ
Q2= M×L
= 1×340.000
= 340.000J
= 340 KJ
Q3= M×Cair× Δt
= 1×4200×80
= 80×4200
= 336.000 J
= 336 KJ
C air = 4200 J/kg'C
C es = 2100 J/kg'C
L es = 340.000 J/kg
Dit : Q ?
Jwb :
Q = m.c.Δt
= 1 kg.2100 J/kg'C.5'C
= 10.500 J
Q = m.L es
= 1 kg . 340.000 J/kg
= 340.000 J
Q = m.c.Δt
= 1 kg.4200 J/kg'C.80'C
= 336.000 J
Jadi kalaor yg diperlukan adalah :
10.500 J + 340.000 J + 336.000 J = 686.500 J
maaf ya kalau salah
