Temperature indicate kinetic energy density in molecular vibration. Over phase change, energy go to motion and fight against molecular interaction make it mobile.
Liquid is more mobile in compare to solid
Vapour is more mobile in compare to liquid.
Molecular vibration (temperature) stay the same while the energy input go to mobility (latent heat).
As matter changes from solid to liquid (in other words when solid matter melts) the temperature remains constant. After all the solid has melted, the temperature of the matter may begin to rise again if the environment is warmer than the melting point of the solid.
When ice at 0°C melts to form water at 0°C, the heat energy supplied goes into breaking the hydrogen bonds between the water molecules in the ice. This process is called latent heat of fusion, and it does not raise the temperature of the substance; instead, it changes the state from solid to liquid. The temperature remains constant at 0°C until all the ice has melted.
It goes through a physical change, because there is no mixing it with something to create a new substance. You could use melted wax just as you did before it melted, if you wanted to.
If a solid piece of naphthalene is heated and remains at 80°C until it is completely melted, you know that 80°C is the melting point of naphthalene. At this temperature, the solid phase transitions to the liquid phase, absorbing heat without a change in temperature until the entire sample is melted. This characteristic behavior is typical for substances during phase changes, where energy input goes into overcoming intermolecular forces rather than increasing temperature.
because it is a physical change because if you leave the ice to melt and you but it( the liquid) in the fridge/freezer it will turn solid again this process reapeats itself,it goes again and again
liquid to solid
The energy that goes into temperature change is being used to change the state of the water, and until the transition is complete, it will not change temperature. The same goes for turning liquid water into a vapor. It is called the "latent heat", and sometimes "heat of fusion".

When solid ice becomes liquid, the temperature goes higher.
Yes the volume of ice changes when the ice melts. In fact the volume of ice goes on increasing up to 0 degree Celsius and when the ice melts completely the volume of ice decreases on the contrary. Yes because when ice freezes, it expands and when it melts, it gets smaller.

No, it is the melting point. Ice changes to water when it melts, not when it boils.
It goes from the solid state to the liquid state.
both. It depends what substance it is. For example: solid water (ice) melts into liquid water (water) and then that melts into gas water (water vapour). Another example is that frozen carbon dioxide (c02)which is a solid also known as dry ice, melts into c02 gas hence the name dry ice because when it melts it goes straight into a gas state.

The freezing point of a substance is lower than its melting point because freezing involves the removal of thermal energy to transition from liquid to solid, while melting requires adding thermal energy to transition from solid to liquid. The freezing point is where the substance goes from a higher energy state (liquid) to a lower energy state (solid).
