they spred out
As the atoms of the heat/air pass into the atoms of the ice cubes, the ice cube's atoms start to lose its structure. So the atoms move into a liquid structure, or melt.
The ice melts and the water gets cooler.
The particles start moving, and it melts. After it melts, it can evaporate if it gets to hot. For example: an ice cube
No, when an ice cube melts it transforms from a solid state to a liquid state without losing or gaining mass. This is because the molecules in solid ice and liquid water are the same; only the arrangement of the molecules changes.
When it melts it is a liquid![:
Imagine a solid cube. Even though you can't see it, the atoms are vibrating just VERY close together. Imagine the cube is solid metal so it would be very dense. Now what would happen if you heated the cube until it started to melt? The metal would become LESS dense as it liquified because the atoms would now be more spread out. The same thing happens with gases. The higher the temperature, the more movement of the atoms and the more movement, the less dense.
a ice cube melts when it heats up
No, it becomes a liquid when it melts.
The water level lowers. See the Related Question below for additional info.

water
No, not at all- the rate of melt of an ice-cube is entirely down to temeprature.
