Heat is applied to water to raise the Kinetic energy of the individual molecules so that they eventually break away from the surface of the liquid state in ever increasing numbers.

Why considerable heat energy is needed to convert 1g of water into 1g of steam at 100c without any change in temperature taking place?
There is heat needed to transform the configuration of liquid water to gaseous state. This is change of state energy changes the configuration without changing the temperature.
When water vapor loses energy what phase change occurs?
When water vapor loses energy it "turns" into a liquid
Is energy required for each phase change?
Yes energy reqired during each phase change process. solid to liquid(water) = 333.7 Kj/kg liquid to vapour(water) =2257.1Kj/kg
How do you change solid water to liquid and liquid water to gas?
You can change both of these by increasing or decreasing the speed of the molecules (kinetic energy), or by increasing or decreasing the heat applied (thermal energy). If you want to melt ice, you can increase the kinetic energy by increasing the thermal energy. The opposite occurs if you want to freeze water.
What is the definition of the term 'latent heat'?
Latent heat is the amount of energy that is needed to change the state of matter. Either from a solid to a liquid, from a liquid to gas or vice versa. For example if you boil a kettle of water, energy or latent heat is added to the water from the element within the kettle. The water will heat up and eventually turn to steam.
What is the name of heat energy that changes ice into water and water into steam?
Latent heat is the measurement of energy needed to change the state of a substance at its melting point or boiling point. The latent heat of fusion of water is the amount of energy needed to change a fixed amount of water from a solid to liquid at 0 degrees C. this works out to be more than 800KJ of heat energy. The latent heat of vaporization of water is the amount of energy needed to change a fixed amount of water from a liquid to a gas at 100 degrees C. this is more than 1200KJ of heat needed to be absorbed.
How a change in energy can change into liquid water?
by boiling the water or putting it in the sun
What do you call the amount of energy needed to change a material from a solid to a liquid. propane or water?
Heat of fusion. (I have no idea what the "propane or water" part is supposed to mean.)
Which evaporates faster hot water or cold water?
Hot water. Higher temperature means more kinetic energy, and energy is needed to change phases from liquid to gas (evaporation.)
What energy required to go from liquid to gas?
No. Energy is require to change it from liquid to gas. When water goes from gas to liquid it releases energy.
Why considerable heat energy is needed to convert 1g of water into 1g of steam at 100c without any change in temperature taking place?
There is heat needed to transform the configuration of liquid water to gaseous state. This is change of state energy changes the configuration without changing the temperature.
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.
What is the amount of energy can change a solid phase to a liquid phase?
Every element has its own energy requirement to change a solid to liquid form. This energy , for water. is 80 calories (333 Joules) to turn a gram of ice to liquid water.
A materials heat of funsion gives the ammount of energy needed to?
The heat of fusion, also known as the enthalpy of fusion is how much energy is required to melt a solid to a liquid. This is the energy required to change the phase of the material - not the temperature. In fact at the melting point the heat capacity becomes infinite because all the energy is being used to change state and not temperature.As energy cannot be created or destroyed it is reasonable to assume it is the same amount of energy for a liquid to turn into a solid, which it is.So if energy is needed to change the phase of ice into water, the same amount of energy is released when water changes back into ice.
What is needed in order for the water vapor to change to liquid water?
It needs to be cooled down to condensate.
When water vapor loses energy what phase change occurs?
When water vapor loses energy it "turns" into a liquid
When energy is added to a liquid and it changes into a gas it is called?
When enough energy is added to a liquid for it to change to a gas, the liquid has reached its _______________
