Question
A 82.46 gram copper metal is heated
to 138.5°C and dropped into 110.48 gram of
water at an initial temperature of Tw. When
equilibrium is reached the temperature of
copper-water mixture is 25°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) =
