A 350.0 gram sample of copper is initially at 25.0C. If the sample absorbs 12.50 kJ of heat from its surroundings, what is its final temperature? cs(Cu) = 0.386 J/g°C
The amount of heat absorbed , Q = mcdt
Where
m = mass of copper sample = 350.0 g
c = specific heat capacity of copper = 0.385 J/goC
dt = change in temperature = final - initial
= t - 25
Q = heta absorbed = 12.50 kJ
= 12.5x1000 J
= 12500 J
Plug the values we get
12500 = 350 x 0.386 x (t-25)
t = 117.5 oC
Therefore the final temperature is 117.5 oC
