When water goes solid (freezes), the molecules get "locked" together to form the solid phase. These molecules can't move around like they can in liquid water because they are interconnected and immobile within the lattice. Most solids exhibit the property of atomic or molecular immobility, though is it is possible for some materials to diffuse into or out of a solid structure.
The freezing of water is a physical change. The water stays the same compound.
The formation of dew is a physical change because it involves a phase transition from water vapor (gas) to liquid water (liquid) due to the cooling of air at night. No new substances are formed during this process, and the water molecules remain the same chemically before and after the dew forms.
Evaporation is a change from liquid water to a water vapour.
When ice changes to water, the speed of the water molecules increases. In the solid state as ice, the molecules are held in a rigid structure and have minimal movement. As heat is added, the molecules gain energy, causing them to vibrate faster and break free from their rigid arrangement, resulting in the molecules moving more freely in the liquid state.
A phase change is not a chemical change since the chemical remains the same; water is still water, whether it is in the solid, liquid, or gas phase.
Evaporation is caused by the continuous Brownian movement of water molecules; several molecules gain sufficient energy to escape in the atmosphere.
The molecules begin to release and move into the air more quickly than they condense back into liquid.
When water evaporates, the molecules gain enough energy to break free from the liquid phase and enter the gas phase. This results in an increase in the overall movement of water molecules as they transition from being closely packed in the liquid to being more spread out in the gas phase.
The continuous movement of water molecules can lead some molecules at the surface to escape in the atmosphere as a gas.
Water does change as it melts from a solid to liquid. That's the change. Its molecules speed up and separate from the lattice structure structure of the ice and become fluid. This is called a physical change because the water molecules themselves do not undergo a change. Solid water and liquid water are still water.If you're talking about temperature, the temperature does not change during the phase change. That's because the heat energy is being used to remove water molecules from the lattice structure. Once all of the water molecules a separated, the temperature can increase.
Water condensing is a physical change. It is a change in state from the gaseous phase (water vapor) to the liquid phase (liquid water) without any change in the chemical composition of water molecules.

Yes, as liquid water is heated, the kinetic energy of its molecules increases, causing them to move faster and collide more often. This increased movement and collisions among the water molecules lead to a rise in temperature.
i think the temperature affects the movement of water because if the liquid is cold the molecules come together. Therefore, the water moves slower, and if the liquid is hot the molecules spread apart and move faster.
From liquid water change to solid: freezing.From liquid water change to gaseous: vaporization.From solid water change to liquid: melting.From solid water change to gaseous: sublimation.
It's actually a lot simpler than that. When liquid water boils, some of the water molecules in a liquid state become so energetic that they go into a gaseous state. They remain water molecules, completely unchanged in their internal composition. They just change how they relate to other molecules. The only "gas" that's released during boiling is water vapor. As such, you can reheat the same water a thousand times and you won't get any change in the boiling process (other than loss of the liquid as the water vapor wisps away). The water molecules in a liquid state will become water molecules in a gaseous state, and the process will be the same on the first, second, and thousandth time.
