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.

Energy is released.
When dos temperature happen?
Do you mean dos? And if u do read below...You cannot measure heat directly, but you can detect its effect on a substance. Changes in heat can usually be detected as changes in temperature. Usually, when you add energy to a bunch of atoms they move faster and get hotter. Similarly, if you remove energy from a bunch of atoms, they usually move less and get cooler.Figure P1 aColdFigure P1 bWarmFigure P1 cHotBecause adding heat energy usually results in a temperature rise, people often confuse heat and temperature. In common speech, the two terms mean the same: "I will heat it" means you will add heat; "I will warm it up" means you will increase the temperature. No one usually bothers to distinguish between these.Figure P2aChanging TemperatureAdding heat, however, does not always increase the temperature. For instance, when water is boiling, adding heat does not increase its temperature. This happens at the boiling temperature of every substance that can vaporize. At the boiling temperature, adding heat energy converts the liquid into a gas WITHOUT RAISING THE TEMPERATURE.Figure P2bConstant TemperatureAdding heat to a boiling liquid is an important exception to general rule that more heat makes a higher temperature. When energy is added to a liquid at the boiling temperature, its converts the liquid into a gas at the same temperature. In this case, the energy added to the liquid goes into breaking the bonds between the liquid molecules without causing the temperature to change. The same thing happens when a solid changes into liquid. For instance, ice and water can exist together at the melting temperature. Adding heat to an ice-water slush will convert some of the ice to water without changing the temperature. In general, whenever there is a change of state, such as the solid-liquid or the liquid-gas transition, heat energy can be added without a temperature change. The change of state requires energy, so added energy goes into that instead of increasing the temperature.
Is energy released when water vapor condenses into liquid?
yes heat is released during condensation.
When condensation occurs water changes from what?
Gas (water vapor in the air) to liquid (on the surface).
What happens to the the energy from the sun when it changes liquid water into water vapor?
Evaporation
Boiling water is is what type of energy?
The type of energy which is used to boil water is commonly heat energy. This will result to a changes from the liquid state to gaseous in form of water vapor,.
True or false when ice changes to a liquid it asorbs energy?
true, when ice changes to a liquid it asorbs heat energy .
What is the energy absorbed by one gram of water as it changes from its liquid phase into water vapor known as?
The heat of vaporization. :D
What type of energy is used to boil water?
The type of energy which is used to boil water is commonly heat energy. This will result to a changes from the liquid state to gaseous in form of water vapor,.
When does matter change state?
when water gains or loses heat, it changes its state. When liquid water gains heat, it changes its state from liquid to gas. It becomes water vapor. When solid gains heat, it melts an changes its state from solid to liquid. When gas loses heat, it condenses into liquid. Gas, to liquid. When liquid loses heat, it becomes solid
Does energy flow into or out of water when it is turning into ice?
It must flow out, ice contains less energy than water. You just have to remember that heat is energy, and all energy, no matter what form, eventually winds up as heat. Take heat energy out of water, it gets cooler, and eventually freezes. Add heat energy to ice, it first changes state to liquid, and then starts to get warmer. Keep adding heat energy to it, it keeps getting warmer and warmer. Keep additing heat energy to it, and eventually it changes state to gas ... called "steam". Take heat energy out of the steam, it first changes state to liquid, then gets cooler. etc. etc.
Does potential energy increases or decreases when gas changes to liquid?
The potential energy of a substance decreases when it changes into a liquid. This is because it's losing the heat energy it had when in gas form to become liquid.
How does water transform energy?
Water can only transform into energy by means of a nuclear reaction. Changes in heat energy can transform water into different physical states, such as solid, liquid, or gas. As heat energy is increased, the water will move from the solid to the gaseous state. If heat energy is reduced, the water will move from the gaseous to the solid state.

The energy that gas changes to liquid?
The latent heat of condensation.
