16.25 g of water at 54 C relaeases 402.7 J. What will be its final temp?
leonid [27]
Data:
Q = 402.7 J → releases → Q = - 402.7 J
m = 16.25 g
T initial = 54 ºC
adopting: c = 4.184J/g/°C
ΔT (T final - T initial) = ?

Solving:

Q = m*c*ΔT
-402.7 = 16.25*4.184*ΔT
-402.7 = 67.99*ΔT
\Delta\:T =  \frac{-402.7}{67.99}
\boxed{\Delta\:T \approx -5.92\:^0C}

If: ΔT (T final - T initial) = ?
-5.92^0 =  T_{final} -  54^0
T_{final} = 54^0 - 5.92^0
\boxed{\boxed{T_{final} = 48.08\:^0C}}\end{array}}\qquad\quad\checkmark
