As 390 g of hot milk cools in a mug, it
transfers 30,000 J of heat to the environment. What is the temperature change
of the milk? The specific heat of milk is 3.9 J/g·°C. Show your work.
Temperature change = (30,000 J)/(390g *3.9 J/g degrees C= 10000/(130*3.9)= 10000/(13*39)
= 10000/(507) =19.72 degrees C
