Suppose 0.4kg of water initially at 40.0°C is poured into a 0.3kg glass beaker having a temperature of 25.0°C. A 0.5kg block of aluminum at 37.0°C is placed in the water and the system insulated. Calculate the final equilibrium temperature of the system. Given ( Cw = 4184¹/kg°C, CAL = 900/kg°C and Cg = 837¹/kg°c)​
