How much energy is taken to change water into a solid?
The same amount of energy that is required to change it from a solid to a liquid. About 334.0 kJ/kg.
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
What does the latent heat of fusion represent?
The energy required to melt a substance. (Apex)
When water vapor loses energy what phase change occurs?
When water vapor loses energy it "turns" into a liquid
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 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.

How much energy is required to change 34.71 g of liquid water to steam?
The answer will depend on the temperature of the liquid water and the pressure.
How a change in energy can change into liquid water?
by boiling the water or putting it in the sun
What does the latent heat of fusion represent?
The energy required to melt a substance. (Apex)
What is required to change the state of water?
what is the temperature at which a substance changes from a solid to a liquid called
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.
The change of water from a gas to a liquid?
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. Any mass of liquid water will have a range of energies for the molecules, some will be low energy, others high energy with each collision between the molecules, they either gain or loose energy. If they gain enough energy, they can become energetic enough to escape the liquid as a gas. The higher the pressure, the more energy is required to become a gas. If the liquid water is in contact with some gas - air for example. The liquid will evaporate until the gas is saturated with water vapor. At that point the rate of water molecules dropping out of the gas back into the water (because they don't have enough energy to stay in the gas) is equal to the rate of water molecules escaping from the liquid to become gas. This point is also known as "equilibrium".
When gaseous water condenses back into liquid water to make clouds is heat energy required by the process or is it released?
Energy is released.
What type of energy is required to change ice to water?
Heat
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.
