A cyclical process is reversible. Water falls from the clouds as rain, then the water winds up evaporating and returning to the clouds, then it falls again as rain, and so forth.

When water boils, it evaporates to become steam. If a cold surface is nearby, the steam condenses back into water. Similarly, if water freezes to ice, it melts to become water again if a heat source is introduced.
cooling water is reversible because when you boil water you leave it alone and it will cool back down.
Yes, it is reversible. Hence it is a physical change.
Yes, they are reversible processes (not reactions).

When a substance is boiling, a part af the substance becomes vapor, the vapor is warmer than 100°C but not the liquid part.
I believe you mean the temperature at which water vapor condenses due to cooling. This is the dew point temperature.
Phase state: The liquid water is becoming vapor, from input of heat.
The boiling point of a liquid is the temperature where the vapor pressure is equal to the atmospheric pressure. Vapor pressure increases with temperature, as you heat the water up the vapor pressure keeps increasing until it matches the atmospheric pressure, then it is boiling. Space isn't quite a perfect vacuum, so the boiling point wouldn't be 0, but it would be very very low.

Because the water stays water, its only a phase change.
when water boils the molecules will get a bigger space inbetween them, which forms a gas (water vapor), when you cool down wator vapor the molecules will get closer together and form a liquid (water)

Yes, the boiling of water can be easily reversed by simply cooling the water vapor.
In a closed system, water can be boiled until it produces water vapor (steam). If the steam is then condensed through a coil of tubing and collected in another container, the same volume of water winds up in the second container that you started with originally. An action created and then reversed to it's original point. Note that this is in a closed system.

To reverse boiling, you need to remove energy from the system, i.e. reduce the temperature. Once the steam (gas, vapor) has formed, you can turn it back into liquid by cooling it.
The process is called condensation. It occurs when the water is cooled below its boiling point due to the temperature in the environment cooling it.
