Grade upto college level Thermal Physics

Heat can be transferred from water at 0ºC and atmospheric pressure without causing the water to freeze, if done with little disturbance of the water. Suppose the water is cooled to – 5.0ºC before ice begins to form. Find the change in entropy occurring during the sudden freezing of 1.0 g of water that then takes place.

To find out the change in entropy (ΔS), substitute 1.0 g for mass of the water m, -333×103 J/kg for latent heat of fusion water L (negative sign is taken for convention) and -5° C for temperature in the equation ΔS = mL/T,
