Q. Determine the specific heat and claculate the total heat transfer?
Ans. If a mug full of coffee has about 350 g of liquid inside, how much heat is lost as it cools from 87oC to 25oC? Assume that coffee is made completely of water, which has a specific heat of 4.18 J/goC.
rounding to 2 significant digits we have
So about 91 kJ of heat were lost as the coffee cooled down.
