Intermolecular forces, i.e. hydrogen-bonds, have to be broken down in order for water molecules to escape to the vapor phase. Energy is needed in the process to set water molecules free.
Energy is work. It exists in all matter and is what makes everything move, grow, heat up, change phase, even light is energy. Energy can neither be created nor destroyed. The use and existence of energy is what is making everything happen around you. Take for instance an ice cube. The ice has both potential (stored) energy and kinetic energy. Heat from other energy sources is melting the ice which is then releasing its stored energy to form water. The water is also evaporating at some point to form vapor. All of the phase changes are transfers of energy from the air into the ice or water. The ice has low energy and as more energy is absorbed it melts and then vaporizes. Water vapor has higher energy than ice through this process (which is known as convection). If you continue to add heat (energy) to the vapor it will become steam which has so much energy, it has been used for more than two centuries to drive turbines. When the steam hits the blades of the turbine it causes them to turn, there-by transferring its energy to the turbine and the steam becomes "weaker" or lower energy.
No. It does not need to lose energy, but it may need a lower pressure for ice to form. The freezing point of water is 0 degrees C only at 1 atmosphere of pressure.
That is related to the Law of Conservation of Energy. To boil water, you need to get it hotter, that requires energy, and this energy has to come from somewhere.
When water evaporates, it draws a lot of energy called latent heat of vapourization. It is this demand for energy from evaporating water that causes a cooling effect as it absorbs heat energy from its surroundings.
You need to learn how to type, it makes u look like a retard
Water vapor needs to condense by cooling it.
You need water vapor, kinetic energy, and energy surrounding inside the atmosphere.
Particles are needed because then the water vapor can condense on them
You just need to cool it down.
You just need to cool it down.
i need help

Either evaporation or the water was boiled. But, in general explanation, the molecule of water need certain energy to break its inter molecular force to cause it being vaporized. So if the quantity energy needed is fulfilled, the state is changing from liquid to gas.
False.
False
Moist air is air that contains a large amount of water vapor. It takes a lot of energy to turn water into water vapor, and the same amount of energy gets released when it condenses back into a liquid. It is this energy released by condensation that powers thunderstorms and hurricanes. So in simple terms, moist air holds a lot of latent energy to power storms. Dry air, by contrast holds much less energy, or at least much less that can go in to powering weather systems.
It is important because of all the water vapor that we need.
