Question

why 0 Celsius is the melting point of ice ?

Answer 1

because that time particles get more kinetic energy

Answer 2

Melting point of a solid is defined as the temperature at which a solid changes into a liquid. Melting point of a solid indicates the strength of the force of attraction between the particles of the solid. On heating a solid, its molecules absorb energy in the form of heat and their kinetic energy increases.Ice melts at 0 degrees Celsius. Thetemperature of the reverse change from liquid to solid is called thefreezing point or crystallization point. For most substances the meltingpointand freezing points are equal. ... For ice, the melting point is 0°C or 273K.
