The molecules begin to release and move into the air more quickly than they condense back into liquid.

The movement of water molecules inreases as the inter molecular distance between the molecules is increased
The water vapor then condenses and becomes a liquid again.
When water changes from a liquid to a gas, it is evaporating or boiling. The "heat and energy" of the water molecules increases in the gaseous state. In fact, water molecules must pick up energy to change state from a liquid to a gas. Water molecules that are free to move as a gas have more kinetic energy than water molecules in a liquid form (as long as the liquid is not pressurized). The "heat and energy" of the H2O molecules that are now a gas is higher than that of liquid water.It should be noted that the thermal energy (heat) necessary to cause water to change state and become a liquid must come from somewhere. In evaporation, the energy necessary for the water molecule to escape from the liquid comes from the liquid. The liquid cools. We know that if we wet our finger and blow on it, it feels cool because evaporating water cools liquid water from which it escapes. That evaporating water has taken energy from the liquid water.In the case of boiling, water molecules take energy from liquid water, but the liquid water might not be cooling. It probably isn't as that liquid water is having thermal energy (heat) pumped into it by a heat source of some kind. Turn on a burner or element on the range under a pan of water and the water will begin warming until it's boiling. As water boils off, it is taking thermal (heat) energy with it, but the remaining water doesn't cool down as the heat source continues to add more thermal energy.
Liquid water molecules exhibit a greater amount of motion than ice molecules.
you can change liquid water to water vapo by putting the water in a pot and heating up the water then when the boiling is done you will see the water vaper on the cover and that how you change the liquid water to water vaper
By heating the water. Boiling it, which would turn it into steam (a gas). The process of changing liquid water into a gas is called evaporation. Energy is added to the liquid water - generally in the form of heat. When enough energy is added, it allows the most energetic molecules at the surface of the liquid to break free of the liquid and enter the gas phase. The more energy that is added, the more water molecules will have enough energy to move into the gas phase. If enough energy is added, all the molecules will leave the liquid and from then on adding energy will just make the gas warmer. Another way to change liquid water into gas is to drop the pressure above the liquid. In this case, it takes less energy for the molecules in the liquid to get away from the liquid so some of them will already be energetic enough to get away.
Evaporation is caused by the continuous Brownian movement of water molecules; several molecules gain sufficient energy to escape in the atmosphere.
The continuous movement of water molecules can lead some molecules at the surface to escape in the atmosphere as a gas.
because the water molecules form together to form a liquid. molecules of water in the air (Vapour), form on a surface to form a liquid.
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.
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.
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.
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 movement and the energy of the molecules increase at high temperature and some molecules can escape from the liquid.
Water molecules are already in liquid form.
When water freezes, the movement of the molecules in the liquid slows down.... Causing the water to become a solid.. In this case, it is called ICE.
Condensation. The transformation of water vapours in liquid water is called condensation, a change of phase.
