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.
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.
What type of phase change is evaporation?
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.
What is the phase change from liquid to gas?
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.
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
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 to snow molecules during phase change?
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.
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.
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.
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 type of change occur when water changes from a solid to a liquid?
its a phase change

What does energy do during 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, resulting in a change in the physical state of the substance (such as from solid to liquid or liquid to gas).
When the molecules in a body move with increased speed it is possible that the body will change from what to what?
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.
What is a substance called when it change from solid to liquid?
This physical phenomenon (a change of phase) is called melting; during melting the chemical nature of molecules is not changed.
