Question

Caculati temperatura pe care a avut-o aluminiul daca temperatura de echilibru a fost 40°C.
C=500J/K
m apa=200 g
t apa=20°C
c apa=4180 J/Kg•K
m Al=100g
c Al=920 J/Kg•K
t=40°C
m Al•c Al•deltaT Al=m apa•c apa•deltaT apa+C•deltaT apa=

Answer 1

Qcedat=Qprimit
c1m1delta(t1)=c2m2delta(t2)
t1=c2m2delta(t2)/(c1m1)+t
t1=4180*20*0,2/(920*0,1) +40=181+40=221 C
