When the water is heated, its molecules get additional kinetic energy due to it. This results in their increased velocity. As their kinetic energy gets increased, they try to overcome the force of attraction between themselves and eventually water changes into water vapour.
Potential Energy
It forms covalent bonds between hydrogen and oxygen. The energy is released when the bonds are broken through electrolysis.
When water freezes, the energy that is lost is released into the surroundings as heat. This heat is dissipated into the environment, causing a slight increase in temperature in the surrounding area.
This phenomenon is called evaporation. Water molecules at the water surface gain sufficient energy to be released in the atmosphere.
As water vapor condenses to form a cloud, the energy that was in the water vapor is released into the atmosphere in the form of latent heat. This released energy helps to fuel the process of condensation, where water vapor changes into liquid water droplets that make up the cloud.
The things that happens to the energy level of solid as it become liquid water is that the liquid has more energy than solid do. Simple as that! BY: ANONYMOUS :)
The energy supplied during water evaporation is used to break the intermolecular bonds between water molecules, allowing them to escape as vapor. This energy is known as latent heat of vaporization. It does not raise the temperature of the water, but instead is stored in the water vapor as potential energy until it is released when the vapor condenses back into liquid water.
When electrical energy is added to water it creates electric shock.
The energy of water molecules is increased to allow evaporation.
It condenses forming water.
When water freezes, thermal energy is released from the water as it changes from a liquid to a solid. This released energy is responsible for lowering the temperature of the water to its freezing point and then further to form ice.
