A 84.59 gram copper metal is heated to 138°C and
dropped into 112.64 gram of water at an initial
temperature of Tw. When equilibrium is reached
the temperature of copper-water mixture is
25.4°C. Calculate the initial temperature of water?
If the specific heat of copper is 385 J/kg°C and
Specific heat of water is 4186 J/kg°C.
Initial temperature of water in (°C) =
