Mixing Water 1. 460 cm3 of water at 83°C is mixed with 115 cm^3 of water at 8°C. Calculate the final equilibrium temperature, assuming no heat is lost to outside the water. Equilibrium temperature: (answer in Celsius) 2. Imagine now that one tried to repeat the same measurement, but between the time that the 460 cm3 of water was measured at 83°C and the time it was mixed with the 115 cm^3 of water at 8°C, the warmer water had lost 4600 cal to the environment. Calculate the final equilibrium temperature assuming no heat loss after mixing occurs. Equilibrium temperature after initial heat loss: (answer in Celsius)
