Dik:m=1kg c es=2100J/kg°C L es=336000J/kg c air=4200J/kg°C dit:Q total jb:Q1=m.c es. ΔT = 1x2100x(0-5) =10500J Q2=m.L es =1x336000 =336000J Qtotal P-Q-R=Q1+Q2 =10500+336000 =346500J <D> maaf jika salah
c es=2100J/kg°C
L es=336000J/kg
c air=4200J/kg°C
dit:Q total
jb:Q1=m.c es. ΔT
= 1x2100x(0-5)
=10500J
Q2=m.L es
=1x336000
=336000J
Qtotal P-Q-R=Q1+Q2
=10500+336000
=346500J <D>
maaf jika salah
