Saturated steam is gas-phase water that is at its condensation threshhold. That means that if the temperature is lowered or the pressure is increased, you will see condensation. An example of this would be boil-off steam in a pot: as soon as it hits the cooler surface of the pot lid, it condenses again. This constrasts with superheated steam, which is above the saturation point due to being heated to hotter than the boiling temperature at the given pressure.
hot air. ^^Close. It is actually steam or the gaseous form of H2O (water). As the water is heated it changes from a liquid to a gas. Since the heat is coming from the bottom (in a pot) and the top of the water is cooler, the gas forms bubbles.
Boiled watr from a kettle has an average temperature of 99 degrees celcius.
boling water is hot steam comes out of the pot you,if you touch it it well hurt
When water boils, the bubbles are made of water vapor. Water is changing from the liquid phase to the gas phase, but it doesn't change all at once, so you get bubbles of gas inside the liquid. The phase change will happen first at the location where heating is taking place, so if you have a pot on a stove, the bubbles will form at the bottom of the pot, and then rise to the top.
When a pot boils and steam is given off, it indicates that the water in the pot has reached its boiling point, which is 100°C (212°F) at standard atmospheric pressure. The steam is water vapor produced by the boiling water turning into a gas.
A good example of a simple Physical Change occurs in a tea pot. The hot, liquid water boils and goes off as steam. Steam is still water (no chemical change,) but is now a gas.
Yes, water boils faster with a lid on the pot because the lid helps to trap heat and steam, increasing the temperature inside the pot and speeding up the boiling process.
Water boils when placed on a natural gas burner. The heat from the burner transfers to the pot, heating the water until it reaches its boiling point and turns into steam.
Steam from your tea pot condensing into water.
It is easy to prepare distilled water at home. Simply fill a large pot with water and place a collection container inside the pot. As the water boils, the steam is collected inside the collection container. This collected steam is distilled water and it should be stored in a sterile container.

A watched pot never boils does not have an express origin. It is called an idiom. It means something else besides what it implies.
Yes, boiling water in a pot on a stove creates water vapor. As the water boils, it transitions from liquid to gas form, producing steam or water vapor.

When you boil water and then later come back, and take the lid off the pot and steam comes out, then you have evaporation
When someone boils a pot of water, heat energy is transferred to the water from the heat source. This causes the water molecules to gain enough energy to overcome the attractive forces holding them together and turn into steam. The temperature of the water remains constant at the boiling point until all the water has been converted into steam.
