= 0,2 kg x 2100 J/kgC x 10 C
= 4200 J
Q bc = m L
= 0,2 x 340.000
= 68.000 J
Qac = 4200 J + 68000 J
= 72200 J
C es = 2.100 J/kg'C
C air = 4.200 J/kg'C
L es = 340.000 J/kg
Dit : Q ( A - C ) ?
jwb :
Proses A - B
Q = M.C es.Δt
= 0,2 kg × 2.100 J/kg'C ×10'C
= 4.200 J
Proses B - C
Q = M.L es
= 0,2 kg × 340.000 J/kg
= 68.000 J
Prose A - C
= 4.200 J + 68.000 J
= 72.200 J
