When an ice cube melts, heat is transferred from the external environment to the frozen water, causing the molecules to move more quickly. The moving molecules contract, forming liquid water.
The water level remains the same after the ice cube melts because the volume of the ice cube is already accounted for in the water level when it is frozen. When the ice melts, it simply changes state from solid to liquid without changing the overall volume in the glass.
There is no ice cube that never melts under normal conditions. However, there are materials like Pykrete, which is a mixture of sawdust and ice, that melt at a slower rate compared to regular ice cubes.
The water level will decrease slightly when the ice cube melts, but the overall volume will remain constant. The melted ice will just fill the space that the ice cube previously occupied, so the glass will not overflow.
If the ice cube melts, the cork will float on the liquid water that was previously frozen as ice. Cork is less dense than water, so it will float rather than sink.
Its actually quite simple. The answer would be Anomalous expansion of Water, which means that the volume the Ice cubes are consuming in a glass filled upto the brim is more than water alone. When Ice melts and comes back into water form, it uses lesser volume (space) in the glass. Hence it does not allow the glass to overflow as the person pouring into the glass had poured in keeping into view the level of the ice (which uses more volume).
It is of course liquid!

It changes from a solid to a liquid.

If you put a ice cube in a pan in a warm room the two physical properties that will change would be shape. Another property would be density.
When it melts it is a liquid![:
on its own
As an ice cube melts, it transitions from a solid state to a liquid state. This means that its shape changes as the solid structure breaks down and the molecules move more freely, conforming to the shape of the container it's in.
