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.
No, boiling water to make steam is a physical change, as it can be reversed by cooling the steam back into water. The water molecules remain the same substance throughout the process.
Steam, as in water steam, is formed when water reaches over the boiling point (100 degrees centigrade). The water will start to evaporate, to make water vapour, and then join the air particles in the air. Whenever there is a cold surface nearby, (such as a window) the water vapour will hit the surface and then condense (turn back into a liquid). Condensing is a process where the water vapour is cooled down to make a liquid. This process is sometimes recognised as boiling and condensing.
When energy is added to water at 100°C, the water will undergo a phase change from liquid to vapor (steam) without a change in temperature. This process is called vaporization or boiling. Once all the liquid water has converted to steam, further addition of energy will increase the temperature of the steam.
Boiling hard water does not make it soft. Boiling water only removes some impurities and kills bacteria, but it does not change the mineral content that makes water hard. To soften hard water, a water softener system is needed.
When boiling water to make hot chocolate, the water molecules gain energy and begin to move faster, causing the water to increase in temperature. Eventually, the water reaches its boiling point, at which it starts to evaporate and turn into water vapor.

No. Steam is just water.
Yes, boiling water to make steam is a physical change. This is because the water undergoes a change in state from liquid to gas without any change in its chemical composition.
Yes, you can make distilled water at home by boiling water and collecting the steam that condenses back into liquid form.
You can make sea water safe to drink by boiling it. This will get rid of all the minerals in the water. I hope this helps you. You have to catch the steam from the boiling, that's the only safe part.
The boiling point of water is 100 degrees celsius. The water will evaporate at boiling point. By the way what do you mean "what happens to the temperature of boiling water" if you think about it, it does not make sense.

Boiling it and catching the steam makes it safe. The steam will not have the salt in it so it will be safe to drink. So all you need to do is figure out a still arrangement to catch the steam and allow it to cool itself back into water.
Water turns into steam by boiling, which means the water temperature rises above the boiling point (about 100°C in most cases, but it depends on the air pressure). Steam turns back into water by condensing, which means the temperature drops back below the boiling point.
Boiling water with the lid on will make it boil faster because it traps the heat and steam, increasing the temperature inside the pot.
There are a couple of ways to make "culinary steam". The first is by immersing a food, like rice in water, covering the pot and boiling it. But there is also something called a "bain Marie". It's a simple oven steamer. The dish to be cooked is placed in another vessel and placed in the oven. The holding vessel is filled with water and the dish is cooked at a constant temperature (the boiling point of water) and the top steamed at the same time. There are also steamers like rice cookers and perforated trays that can be suspended above boiling water while the food in the trays is steam cooked. The Chinese use bamboo baskets suspended over water boiling in a wok for the same purpose.
The way to make steam is very simple. All you have to do is put a shallow amount of water at the bottom of a pot, then put the lid on it, then turn the stove on hot enough to bubble the water.
