If you pour whisky over ice, the ice will cool the drink, but it will also dilute it. A solution is to use whisky stones. Suppose Ernest pours 55 g of whisky at 22°C room temperature, and then adds three whisky stones to cool it. Each stone is a 32 g soapstone cube that is stored in the freezer at –15°C. The specific heat of soapstone is 980 J/kg • K; the specific heat of whisky is 3400 J/kg • K. What is the final temperature of the whisky?
