What happens to the size of the molecules during a phase change?
During a phase change, the arrangement of molecules changes while their size remains the same. For example, when a solid transitions to a liquid, the molecules rearrange into a more disordered state, but their actual size does not change.
What happen to the ices molecules during this phase change?
The ice (solid) become water (liquid); the distances between molecules are decreased during the change of phase, also the attraction forces.
Where do molecules go when ice melts?
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.
When the physical state of a substance changes during a phase what happens to the temperature of the system?
The temperature remain constant during a change of phase.
Is the amount of water the same after the solid ice change phase to its initial form as an ice water?
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.

Which phase change occurs during evaporation?
The phase change that occurs during evaporation is when a liquid changes into a gas. This process happens when the molecules of the liquid gain enough energy to escape into the air.
During which phase change does the average distance between molecules always increase?
During the phase change from a liquid to a gas, the average distance between molecules always increases.
What happen to the ices molecules during this phase change?
The ice (solid) become water (liquid); the distances between molecules are decreased during the change of phase, also the attraction forces.
What happens the temperature during a phase change?
nothing
What happens to energy during a phase change?
During a phase change, energy is either absorbed or released as heat without causing a change in temperature. This energy is used to break or form intermolecular bonds between molecules, rather than increasing the average kinetic energy of the molecules.
What happens to the energy during a phase change?
When energy is added during a phase change the energy is used to break molecular bonds.
Where do molecules go when ice melts?

What happens to the energy added during the phase change?
When energy is added during a phase change the energy is used to break molecular bonds.
What happens to the energy added during a phase change?
The added energy is used in the phase change to break intermolecular bonds.It is used for the phase change. ~ APEX
When the physical state of a substance changes during a phase what happens to the temperature of the system?
The temperature remain constant during a change of phase.
During what phase change does the arrangement of water molecules become most orderly?
During fusion, or the formation of a solid, as in liquid water turning to ice.
