1. 400 cm3 of water at 92°C is mixed with 120 cm3 of water at 18°C. Calculate the final equilibrium temperature, assuming no heat is lost to outside the water.

Equilibrium temperature:   °C

2. Imagine now that one tried to repeat the same measurement, but between the time that the warm water was measured and the time it was mixed with the cooler water, the warmer water had lost 4800 cal to the environment. Calculate the final equilibrium temperature assuming no additional heat loss after mixing occurs.

Equilibrium temperature after initial heat loss:   °C
