At 0 degrees Celsius it requires introduction of energy to change ice to water and removal of energy to change water to ice This energy goes not into heat production or deletion but into the change of state of the matter, i.e., solid to liquid or liquid to solid depending upon whether energy is being added to or removed from the system respectively. Thus there is this kind of neutral zone where water can exist both as a liquid and as a solid The same sort of situation exists at 100 degrees Celsius with respect to liquid water and steam.

Zero degrees celcius is the temperature in wich the transition from liquid water to ice or vica versa happens, the temperature needs to be a little above or below 0 to actually melt or freeze

0 degrees Celsius is the point at which it changes from solid to liquid. In that sense if the temperature is being lowered, the 0 degrees Celsius is the point at which it begins to form into a solid. If the temperature is being raised, 0 degrees celsius is the temperature at shich it turns from solid to liquid. It is, you could say, the "middle man".

This is not techincaly correct. Water enters its transitional phase into ice when it COOLS BELOW 0 degrees Celsius.
Ice would enter its transitional phase to water when it is HEATED ABOVE 0 degrees Celsius.
0 degrees C is just the temp that the changes occur.

Even at STP, water can exist below 0 deg C. this is called sub-cooling. There is a significant problem in aviation called rime icing. Rime is a white or milky opaque granular deposit of ice. It occurs when supercooled water droplets strike an object at temperatures at or below freezing. Factors favoring the formation of rime are small drop size, slow accretion, a high degree of supercooling, and rapid dissipation of latent heat of fusion. Rime is a result of freezing drizzle and looks like frost in a freezer. Rime icing which forms on aircraft can seriously distort airfoil shape, therefore diminishing lift and performance. Rime icing is more likely to form in stratus-type clouds with temperatures between 0°C and minus 22°C. When formed in cumuliform-type clouds, temperatures range from minus 9°C to minus 15°C and are accompanied by clear icing which is then termed mixed icing.

suppose you are standing in the door of your house- u may go in or come out. The point of exit/ entrywill always be the same- the door, ie.
You may call it 'coming from outside I have to cross that door' or 'going from home I have to cross that door'. Its all the same point.
Similarly, the melting point of solid water (ice)= freezing point of liquid water= 0 deg celsius.

0 is the freezing/melting point.If the temperature rises the ice melts. If it lowers the ice freezes.

ice melts little after 0 celcius [ temperature greater than zero.

With the understanding of the concept of Latent Heat, it can be understood properly. Better to refer to a text book.
