First, we need to account that the heat was REMOVED so in our calculations it should be NEGATIVE. Next, we can see that the specific heat given is in J/g-oC so we need to convert the heat removed from KJ to J.
Next, we use the equation below to solve for the Final temperature (Tf)
When Karl Kaveman adds chilled grog to his new granite mug, he removes 10.9 kJ of energy from the mug. If it has a mass of 625 g and was at 25°C, what is its new temperature?
Specific heat capacity of granite = 0.79 J/g • °C.
A. 3 °C
B. 14 °C
C. 22 °C
D. 47 °C
E. None of these choices is correct.
