Water in it's gas state is commonly called "steam".
Water vapor?
The process of water turning into gas (water vapor) is called evaporation.Heating water into water vapor is called boiling. High-temperature water vapor is called steam.The water has become water vapor.
A substance changes from the liquid state to the gas state when enough heat is added for the temperature to be equal or greater than its boiling point. Example: Water begins turning into a gas when it reaches 100 degrees C, which is the boiling point of water
the name for water in liquid form is water
The process of changing liquid water into a gas is called evaporation. Energy is added to the liquid water - generally in the form of heat. When enough energy is added, it allows the most energetic molecules at the surface of the liquid to break free of the liquid and enter the gas phase. The more energy that is added, the more water molecules will have enough energy to move into the gas phase. If enough energy is added, all the molecules will leave the liquid and from then on adding energy will just make the gas warmer. Another way to change liquid water into gas is to drop the pressure above the liquid. In this case, it takes less energy for the molecules in the liquid to get away from the liquid so some of them will already be energetic enough to get away. Any mass of liquid water will have a range of energies for the molecules, some will be low energy, others high energy with each collision between the molecules, they either gain or loose energy. If they gain enough energy, they can become energetic enough to escape the liquid as a gas. The higher the pressure, the more energy is required to become a gas. If the liquid water is in contact with some gas - air for example. The liquid will evaporate until the gas is saturated with water vapor. At that point the rate of water molecules dropping out of the gas back into the water (because they don't have enough energy to stay in the gas) is equal to the rate of water molecules escaping from the liquid to become gas. This point is also known as "equilibrium".
Condensation is water moving from a gas to a liquid state
Gas state of water is steam
Gas state of water is steam
Gas state of water is steam
water vapors
When water changes from a gas to a liquid it is still called water, but I don't think that was your question. The process of changing water, or any substance for that matter, from it gaseous state to it liquid state is called condensation,
The gas state of H2O is called water vapour. However, it is not steam, as steam is a collection of small condensed water droplets.
What is called the change of state of liquid to gas
condensation
Water that is in a gaseous state is called water vapouror steam.
From water at solid state or ice change to liquid the process is called melting. From water as solid to gas the process is called sublimation. From water as liquid to gas the process is called evaporation. All these 3 processes involve change of state and absorb heat.
In the liquid state, water is water. In a solid state, water is ice. In a gas state water is called water vapor.
Vapour. (Or evaporation.)
