Why does steam take up more room than liquid?

Answer 1

First we must understand that there is a direct correlation between temperature of a substance and the amount of molecular movement. At absolute zero the molecules do not move at all. As the temperature increases, so does movement. As movement increases, so does temperature.

Water has two hydrogen atoms and one oxygen atom. The oxygen of one water molecule has two lone pairs of electrons. Each can form a hydrogen bond with the hydrogen on two other water molecules. This repeats so that every water molecule is bonded to four others (two through its lone pairs and two through its two hydrogen atoms.) These bonds restrict movement.

Since heat makes molecules move and the hydrogen bonds resist this movement, it takes more energy to break the bonds of liquid water and force the molecules apart into a gaseous state. Once transformed to a gas, there are fewer bonds to overcome, so the energy to make the molecules move (heat them up) is lower.

Because steam is actually hotter than water AT FIRST, but after it gets into the atmosphere it lowers which is why it condensates (condenses) on a wall or glass or something. Because it lowers heat, it sticks.

Answer 2

Both steam and liquid are made of the same things: 2 atoms of hydrogen and 1 atom of oxygen. The only thing that differs between them are the amount of energy in each molecule. The molecules in a liquid are more energetic than a solid but less than a gas. In a gas, they are more energetic than the a liquid and a solid.

Entropy is the amount of disorder in a substance. Therefore, which is more organized? A liquid or a solid?

Obviously it is the liquid, because it is has less energy. So steam (a gas) has more entropy, because it is less organized.

Entropy is a concept that can get confusing and can seem backward. Just remember: entropy refers to disorder and confusion and disorganization.

Answer 3

because steam is hot that makes the water boil then the water goes up and up that makes the steam go up to so it takes up a large amount of space

steam have a lower density than water?
