1.	'Rate of Melting = Rate of freezing'' When is the above condition achieved ? Explain with an example.
Answer» Solution :Let US consider the melting of ICE in a closed container at 273 K. In the PROCESS the total number of WATER molecules leaving from and returning to the solid phase at any instant are equal. If some ice-cubes and water are placed in a thermos flask (at 273 K and 1 at, pressure). then there will be no change in the mass of ice and water. At equilibrium, `{:("Rate of meltingRate of FREEZING"),("="),("of iceof water"),(""H_(2)O(S)hArrH_(2)O(l)):}` The temperature at which the solid and liquid phases of a substance are at equilibrium is called the melting point or freezing point of that substance.
