Just because it is in a different state of matter doesn't mean it has a different weight. One ton of liquid water is equal to one ton of gas water.
liquid (water) and gas (air)
water in the form of gas is water vapor.
The reaction equation is: 2H2 + O2 = 2H2O So one need two volume part of hydrogen and one volume part of oxygen to form water.
I think the term you are looking for is condensation, this is pretty much the opposite of evaporation and is what you see when you see drops on windows
Four electrons reduce one molecule of oxygen gas to form water
Water. Water vapor occurs when water evaporates, or heats up so much that it turns into a gas. This gas is called water vapor, or steam, although steam is hot water vapor.
Water vapor is water in the form of a gas.
That completely depends on the temperature of the water when the gas flame is first ignited, which you've neglected to mention.
When water is in the form of a gas, it is called water vapour.
When water is in the form of a gas, it is called water vapour.
A physical change is when something reacts with water to form a gas. For example, when magnesium reacts with water vapor, it will form hydrogen gas and magnesium hydroxide.
solid liquid and gas Solid form: Ice, Liquid form: water, Gas form: water vapor / steam
