Ice is a molecule of water (H2O) in the solid phase.
If the molecules in question have a solid phase, for example water which goes from liquid to solid, namely ice, then least kinetic energy is the solid phase, with minimum kinetic occurring at 0 Kelvin (absolute zero).
Yes, molecules in the gas phase typically move faster than in the liquid phase because gas molecules have more kinetic energy compared to liquid molecules due to the higher temperatures in the gas phase. Additionally, there is more space between gas molecules, allowing them to move more freely and at higher speeds compared to the liquid phase where molecules are more closely packed.
Energy is required to overcome the intermolecular forces holding liquid molecules together. As the liquid molecules absorb energy from their surroundings, they gain enough kinetic energy to break free from the liquid phase and evaporate into the gas phase.
When ice is placed on a plate that is warmer than the ice, some of the heat energy from the plate is transferred to the ice. (This is due to the molecules in the plate transferring kinetic energy to those in the ice. The molecules in the plate crash into those in the ice, losing speed and giving the molecules in the ice more speed). Since the heat energy is transferred away from the plate, the plate cools down. (The ice is not cooling down, it is heating up.)
When an ice cube is melting, it absorbs heat from its surroundings, causing the ice crystals to break down and transition into liquid water. The temperature of the ice cube will gradually increase until it reaches the melting point of 0 degrees Celsius, at which point it will fully melt into water.
The melting of ice is a change of phase, from solid to liquid, a physical processus. The molecules of water (H2O) remain unchanged during the change of phase.
A phase change does NOT chance the total number of molecules. There will be some evaporation and sublimation too. During the time that ice melts there will some molecules that sublimate to water vapor and also some water molecules evaporate to vapor. But the total mass and number of molecules will not change.
Water molecules are closest together in the liquid phase.
The ice (solid) become water (liquid); the distances between molecules are decreased during the change of phase, also the attraction forces.
Yes. But there are many (about 15) different phases of ice. Have a crack at Ice in wikipedia.com.
Ice can float on liquid water.

the ice cube is in a phase of a solid.
During fusion, or the formation of a solid, as in liquid water turning to ice.
The chemical symbol for ice is H2O, which represents the water molecule. Ice is the solid phase of water, where water molecules are arranged in a crystalline structure.
It starts to freeze at 0oC , if heat is still withdrawn from the water: it is needed for the freezing of water molecules from the liquid phase to solid phase (ice) and during this temperature will remain 0oC.
