**Problem**: 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.

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- ^{o}C** 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)
