Best Answer

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.

What is energy and why do you need it?

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.


Does 0 degree C water need to lose energy to become 0 degree C ice?

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.


Why do you need heat to boil water?

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.


If you are standing on a wet floor and when the water evaporates it produces a cooling effect How does the kinetic theory explain the cooling effect?

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.

Does water vapor need a solid object on which to condense?

False.


What caused the water to change from liquid water to water vapor?

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.


Water vapor does not need a solid object on which to condense.?

False


Why do tornadoes and hurricanes need moist air to develop?

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.


Why is Air masses important?

It is important because of all the water vapor that we need.
