They move slower because in a solid the molecule move faster and in a gas they move slower, therefore, they will move slower. :)
During the phase change from a liquid to a gas, the average distance between molecules always increases.
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.
Evaporation is a phase change from liquid to gas, where molecules at the surface of a liquid gain enough energy to escape into the gas phase.
The phase change for liquid to gas is vaporization, which includes evaporation and boiling.Evaporation - The change of liquid molecules on the surface of a liquid to a gas.Boiling - The change of phase at or above the boiling point of the liquid, which takes place at nucleation sites within the liquid.
The added energy is used in the phase change to break intermolecular bonds.It is used for the phase change. ~ APEX
During the phase change from a liquid to a gas, the average distance between molecules always increases.
The ice (solid) become water (liquid); the distances between molecules are decreased during the change of phase, also the attraction forces.
During a phase change from solid snow to liquid water, the snow molecules absorb heat energy and gain enough kinetic energy to break their bonds and transition into liquid form. This process is called melting.
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.
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.
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.
its a phase change
Evaporation is a phase change from liquid to gas, where molecules at the surface of a liquid gain enough energy to escape into the gas phase.
The phase change for liquid to gas is vaporization, which includes evaporation and boiling.Evaporation - The change of liquid molecules on the surface of a liquid to a gas.Boiling - The change of phase at or above the boiling point of the liquid, which takes place at nucleation sites within the liquid.
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, resulting in a change in the physical state of the substance (such as from solid to liquid or liquid to gas).
As the molecules in a body move with increased speed, i.e. increasing kinetic energy, it is possible that the body will change from the solid phase to the liquid phase, or the liquid phase to the gas phase, and in some cases from the solid directly to the gas phase.
This physical phenomenon (a change of phase) is called melting; during melting the chemical nature of molecules is not changed.
