An ice cube at 0.00 °C with a mass of 23.5 g is placed into 550.0 g of water, initially at 28.0 °C, in an insulated container. Assuming that no heat is lost to the surroundings, what is the temperature of the entire water sample after all of the ice has melted?
Mass of ice = 23.5g
Mass of water = 550 g
Initial temperature = 28oC
We will have to find the temperature of the entire water sample after all of the ice has melted?
The specific enthalpy of fusion of water is 333.55 kJ/kg at 0 °C. = 333.55 J g-1deg-1
Heat gained by the ice/water = heat lost by warm water Q = mcΔT
Q is the quantity of heat,
m = mass of water in g,
c is specific heat in J g-1 deg-1 (= 4.184...
