I don't understand how the freezing point of a substance is the same temperature as the melting point of the same substance.
For example, if liquid water freezes at 0 °C how can ice also melts at 0 °C?

Answer:

[tex]\text{The concept of the freezing point and the melting point being the same }\\\text{temperature for a substance can seem confusing at first, but it's quite logical}\\\text{when you understand the process involved.}[/tex]

[tex]\text{See, when a substance undergoes a phase change from solid to liquid, it melts.}\\\text{Conversely, when it undergoes a phase change from liquid to solid, it freezes.}\\\text{Both of these phase changes occur at the same temperature under equilibrium}\\\text{conditions, which means that both processes are happening simultaneously}\\\text{at the same rate.}[/tex]

[tex]\text{Also, you might want to know the concept of 'Latent heat of fusion'. It }\\\text{refers to the amount of heat energy required to change a substance from }\\\text{solid to liquid or vice-versa at constant pressure and temperature. This heat }\\\text{is used to solely break or form intermolecular bonds rather than raising or }\\\text{lowering the temperature of the substance. So, temperature remains }\\\text{at the melting/freezing pint, the temperature remains contant.}[/tex]
