What would be the temperature of 40.0 g of 22°C water mixed with 60.0 g of 80°C water? Answer in degrees Celsius. Here's the logical pathway to find the answer:  The cold water absorbs heat according to Q1 = 40*4.186*(T-22).  The hot water loses heat according to Q2 = 60*4.186*(80-T).  Q1 must equal Q2, so solve for T, the equilibrium temperature.
