Imagine now that one tried to repeat the same measurement, but between the time that the 480 cm3 of water was measured at 79°C and the time it was mixed with the 120 cm3 of water at 9°C, the warmer water had lost 2880 cal to the environment. Calculate the final equilibrium temperature assumning no heat loss after mixing occurs. Please help!!!
