Calculate the temperature found when 10kg of water at 100°C is mixed with 20kg of water at 40°C.

Answer 1

heat lost by warm water + heat gained by cool water = 0

[mass warm water x specific heat water x (Tfinal-Tinitial)] + [mass cool H2O x specific heat H2O x (Tfinal-Tinitial)] = 0
Solve for Tfinal.

Answer 2

From the formula displaced , the T final is : H loss by warm H2O + H gained by cold H2O =0. M C ( T2-T1) + M C ( T2-T1 ) =0 .T final= ... Continue...
