When water changes from a liquid to a gaseous state, its molecules gain energy and move faster, breaking the hydrogen bonds that hold them together in the liquid state. As a result, the arrangement of water molecules becomes more dispersed and random, transitioning from a relatively close-packed configuration to an expansive gaseous state. This increased movement allows the molecules to spread out and occupy a larger volume, leading to the formation of water vapor.
From solid to liquid, from liquid to gaseous, from gaseous to liquid, from liquid to solid, and in sublimation from solid to gaseous or the reverse, chemical properties do not change.
In evaporation, a liquid such as water changes to a gaseous state. In sublimation, a solid such as ice changes driectly to a gas or vapor without going through a liquid state.
No, the chemical structure of water does not change when it changes states. Water (H₂O) remains the same molecule whether it is in solid (ice), liquid, or gaseous (steam) form. The differences in state are due to changes in temperature and pressure, which affect the arrangement and movement of the water molecules, but the molecular composition remains constant.
When water boils it changes from a liquid state to a gaseous state.
When a liquid is heated and changes to its gaseous state, it is called vaporization.

Sublimation. It bypasses the liquid state and changes directly into gaseous state.
water changing to a solid: freezing movement of particles: vibration in fixed positions. arrangement: fixed positions (bonds between every particle). moving closer together water as a liquid: movement of particles: move about (slide past each other) arrangement: close together with no regular arrangement water to gas: boiling movement of particles: free/random movement at high speeds. arrangement: particles move further apart with no bonds between particles.

As a substance changes from a liquid to a gas, the particles move further apart and gain more kinetic energy, leading to increased randomness and higher speed of movement. In contrast, as a substance changes from a solid to a liquid, the particles gain enough kinetic energy to overcome their fixed positions in a crystal lattice and begin to slide past one another, resulting in a less ordered arrangement and increased freedom of movement.
Condensation is the process in which a substance changes from a gaseous state to a liquid state. This occurs when the gas loses energy (usually in the form of heat) and becomes more tightly packed together, forming liquid droplets.
