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·K)

The correct answer is A.The change in temperature is given by:ΔT = Q / (mc)where Q is the energy removed, m is the mass, and c is the specific heat capacity.Plugging in the values, we get:ΔT = -10.9 kJ / (0.625 kg * 0.79 J/(g·K)) = -21.8°CThe new temperature is therefore:25°C - 21.8°C = 3°C
