Why do molecules at the surface of a liquid behave differently from molecules in the interior of the liquid?
In the interior the intermolecular forces of attraction is equal in all directions but the molecules at the surface of liquid experiences unequal intermolecular forces of attraction. the molecules at the surface are free so the adsorb liquid or gaseous molecules
Will molecules go faster and farther when liquid turns to gas?
no, that is the opposite, molecules will move faster and farther apart when the state changes from liquid to gas
What will happen to the water molecules when water boils?
It's actually a lot simpler than that. When liquid water boils, some of the water molecules in a liquid state become so energetic that they go into a gaseous state. They remain water molecules, completely unchanged in their internal composition. They just change how they relate to other molecules. The only "gas" that's released during boiling is water vapor. As such, you can reheat the same water a thousand times and you won't get any change in the boiling process (other than loss of the liquid as the water vapor wisps away). The water molecules in a liquid state will become water molecules in a gaseous state, and the process will be the same on the first, second, and thousandth time.
The rate of condensation depends on what?
As the number of gaseous particles increase, the rate of condensation increases because more and more gaseous particles are coming into contact with the liquid surface.
Why does steam at 100C damage the skin than water at 100C?
I think it's the other way - 100°C liquid water causes more damage than 100°C gaseous water. Liquid water has molecules that are much more densely packed than gaseous water. Since temperature is the measure of average kinetic energy, the molecules in liquid form move just as fast as the molecules in gaseous form. So if you stick your finger in liquid water, much more molecules will hit you. Unless that extra enthalpy of vaporization causes a difference in speeds of the molecules, then that extra energy required to vaporize water will be transferred to you, and you will feel more pain.
What is the process by which molecules at the surface of a liquid absorb enough energy to change to a gaseous state?
Evaporation is the process by which molecules at the surface of a liquid absorb enough energy to change to the gaseous state.
How does liquefaction of gases takes place?
Liquefaction of gases is the process by which substances in their gaseous state are converted to the liquid state. When pressure on a gas is increased, its molecules closer together, and its temperature is reduced, which removes enough energy to make it change from the gaseous to the liquid state.
How are water molecules packed when they are in a gaseous state?
The molecules move freely and rapidly in all directions.

In the interior the intermolecular forces of attraction is equal in all directions but the molecules at the surface of liquid experiences unequal intermolecular forces of attraction. the molecules at the surface are free so the adsorb liquid or gaseous molecules
What is the process that changes water vapor to liquid water?
CondensationCondensation is the process by which water vapor changes to liquid.
Evaporation involves the process of changing water molecules from the liquid state into what of what?
By evaporation liquid water is transformed in gaseous water.
Will molecules go faster and farther when liquid turns to gas?
no, that is the opposite, molecules will move faster and farther apart when the state changes from liquid to gas
Are molecules close together in a liquid?
molecules are closer together in a liquid than a gas but further apart than in a solid
What are the changes involved in boiling water?
A phasechange is occured in water molecules, from liquid state to gaseous state.
Can a liquid substance diffuse in another liquid substance a gaseous in liquid a gaseous in gaseous?
Yes, all of them.

What are the states of water How does it describe the arrangement of water molecule?
The 3 states of water are liquid, solid, and gas. The molecules bind closest together in the solid state and furthest apart in the gaseous state.
