The Molecules(Atoms) stretch their bonds so they spread further apart from each other.
the bonds between the water molecules are broken
The molecules in water are not tightly packed as such flow and spread very easily but when the water turns to ice the molecules in the liquid enlarge ans they tightly packed and thus, when water turns to ice new molecules are not formed.
The water molecules remain unchanged.
When liquid water evaporates and turns into steam, the water molecules gain enough energy to overcome the forces holding them together, becoming a gas. Steam is then released into the air as water vapor, which can condense back into liquid water when it cools down.
The water molecules expand when they are blown out. When this happens, the mixture turns into snow.
the bonds between the water molecules are broken
the water vapor turns to liquid
It turns into water and the molecules becomes less densely packed
The molecules in water are not tightly packed as such flow and spread very easily but when the water turns to ice the molecules in the liquid enlarge ans they tightly packed and thus, when water turns to ice new molecules are not formed.
When the heat is added to water, the atoms in the water particle get enough energy, they end up being so poweful, they are able to pull away from other atoms and bounce around. It's sort of like heating water, the water is getting boiled and the water turns to steam. When energy/heat is taken away from the gas form, the steam turns back into a water form. To make it simple, The molecules get energy from heat.
The atoms speed up building up kenetic energy which forces them apart and that is what turns the liquid into a gas
The water molecules remain unchanged.
The molecules freeze.
The molecules freeze.
It turns to ice or heavy water.
At 277,15K water achieves it's densest packing structure (coordinates to 6 other molecules) At the other temperatures the molecules aren't as densely packed.
molecules that start closing together turn into solid example: think of water, when molecules are loose the water is liquid but when the molecules are packed together the water turns into ice
