A solid is hard and has a fixed shape. Liquid particles are touching but further apart than solids.

They also don't have a regular shape. They move by sliding past each other. The ice cube which was solid has turned into the liquid water because the air temperature is warmer than the freezers.

Which means the ice particles gather heat energy from the warmer air. Therefore the ice particles have enough energy to break apart melt into smaller particle arrangements.

Which means the particles can move more freely. They slide past each other and don't have a regular shape like solids do. This is what happens when the ice cube a solid turns into water a liquid.

The reason an ice cube takes up a much smaller area than it does when it melts is that the once-compact particles have spread out and take up more space.

You might think an ice cube has completely melted when it turns into liquid, but the process can go much further. If the temperature surrounding the liquid reaches its boiling point of degrees Celsius 12 degrees F , the water evaporates and turns into water vapor. The heat gives the liquid particles enough energy to break away from one another until they are sparsely spaced they can't be seen by the naked eye. They are now randomly arranged and can move freely in all directions. If you want to melt ice cubes faster, you have to lower the ice's freezing point — make it melt into a liquid at a lower temperature than normal.
