Well, honey, at 273.3 K, liquid water won't freeze because the Gibbs free energy change for the freezing process is positive at that temperature. In simpler terms, the water is too busy being a sassy liquid to bother solidifying into ice. So, until the Gibbs free energy change becomes negative, that water ain't gonna freeze, no matter how much you beg.
When a liquid is cooled, the kinetic energy of its particles decreases. At a certain temperature, the average kinetic energy becomes low enough for the particles to slow down and form a ordered structure, transitioning from a liquid to a solid state due to the attractive forces between them.
Evaporation is the process by which molecules in a liquid state gain enough energy to enter the gaseous state. It occurs when molecules near the surface of a liquid gain enough kinetic energy to overcome intermolecular forces and escape into the air as vapor.
For a gas to become a liquid, energy must be removed from the system. This is typically achieved by cooling the gas below its condensation point, which causes the gas molecules to slow down and come closer together to form a liquid. The energy removed is used to weaken the intermolecular forces holding the gas molecules apart, allowing them to transition into a liquid state.
Any object above zero kelvin - in other words, any object - has thermal energy. If you cook down a liquid - reduce its thermal energy - it will sooner or later get cold enough to become a solid.
Some vocabulary terms related to energy include potential energy, kinetic energy, thermal energy, renewable energy, and nonrenewable energy.

The change is endothermic.
Evaporation is a phase change from liquid to gas, therefore it involves increased energy and decreased bonding on the molecular level.

In terms of kinectic energy molecules in soilid will have least energy. Molecules in lquid have less energy than in gases. Molecules in gaseous state have maximum energy. Entropy of a substance increases from solid to liquid to gas.
To change a liquid into a gas, the particles in the liquid must overcome the attractive forces holding them together to become a gas where the particles are more spread out and have higher energy. This requires energy input to break these intermolecular forces and increase the kinetic energy of the particles to transition from the liquid phase to the gaseous phase.
Accelerated Freeze Drying
Any object above zero kelvin - in other words, any object - has thermal energy. If you cook down a liquid - reduce its thermal energy - it will sooner or later get cold enough to become a solid.
The heat of fusion is the energy required to change a substance from a solid to a liquid, while the heat of vaporization is the energy needed to change a substance from a liquid to a gas. Both are types of phase changes that require specific amounts of energy to occur.
A loss of energy to the water molecules surrounds at an atomic level causes for the water vapour to condense into a liquid from a gaseous state. If we think of it in terms of energy, to boil and evaporate water, you apply thermal energy- the temperature of the water will rise until it hits 100 degrees Celsius, after which point it will start it's transition into a gas phase from the liquid phase. To take it the other way, as water vapour loses energy (i.e. as it's temperature drops) it will start to condense into liquid water.
we can use water as terms of energy by not wasting it.
