They are able to move freely.
Water and ice can be reversible because they both consist of the same molecules, H2O. When water is cooled down to its freezing point, it forms an orderly crystal lattice structure, resulting in ice. Conversely, when ice is heated to its melting point, the crystal lattice breaks down, turning it back into water.
Salt lowers the freezing point of water by disrupting the formation of ice crystals. The presence of salt in water makes it harder for the water molecules to organize themselves into a solid crystal lattice, causing it to require lower temperatures in order to freeze.
The ice cube melts as the temperature of the kitchen counter is higher than the freezing point of water. The water molecules gain energy from the counter, causing them to break their solid lattice structure and transition into the liquid state.
When ice melts in a glass, it changes from a solid state to a liquid state. The ice absorbs heat from the surroundings, causing the molecules to move faster and break free from their rigid structure. As a result, the ice turns into water.
Ice actually expands as it melts, which is why a floating iceberg will raise the water level as it melts. This is because water molecules in solid ice are locked in a crystal lattice structure, which becomes more disordered and takes up more space as the ice melts into liquid water.

The organized crystal lattice of ice begins to form at 4 °C.

Rather than melts, dry ice evaporates. This process is called sublimation and happens at a slower rate than the melting of water ice.
They are able to move freely.
Water's atoms do not have any repeating patterns. However, ice has a repeating geometric pattern. Ice is a crystal lattice.

It melts rapidly.
It becomes water.
