WebMar 5, 2024 · What happens to molecules of water when water boils? Energy is removed from water in the liquid state. As a result, water's molecules speed up, the empty space between them stays the same, and water changes from a liquid to a gas. This process is exothermic. Energy is removed from water in the liquid state. As a result, water's … WebJan 30, 2024 · When boiling occurs, the more energetic molecules change to a gas, spread out, and form bubbles. These rise to the surface and enter the atmosphere. It requires energy to change from a liquid to a gas (see …
