Energy is entering the system bc to change from solid to liquid there must be heat. Also the particles are now less dense and moving around more.
When a substance changes from a liquid to a gas energy is absorbed. When a substance changes from a gas to a liquid energy is released.
The particles that evaporate from a liquid are on the surface of the liquid.
The particles have most energy in particles in steam. In a gas. the particles move more freely, Therefore, there is more energy in the steam. :D LOL
The particles are no longer fixed by the forces keeping it a liquid
Remove enough heat from the liquid, it changes to a solid- known as freezing.
The particles of the substance gain kinetic energy as they absorb heat energy. Eventually there is enough kinetic energy for the particles to escape the liquid phase, forming the gas phase.
Adding heat will do one of the following, or both: * The temperature of the substance increases. The individual particles move faster; their kinetic energy increases. * The substance changes its state (for example, when ice melts, it changes from solid to liquid). The potential energy of the particles increases.
in my opinion, I don't really know

A liquid changes into a solid state when its particles start losing energy. This is usually due to a decrease in temperature because if there is less heat energy present, there is less kinetic energy produced in the particles. As the particles of the liquid continue to slow down its vibration speed, it becomes a solid. The word for this is known as freezing and the best example for it is the change of state from water (liquid) to ice (solid).

Energy is used when water changes from a solid to a liquid.
