They start to speed up and expand.
the particles are given more energy.
it heats up
Usually by adding heat and/or reducing pressure.
As heat energy is supplied to a liquid, its temperature rises. The rise of temperature causes a rise in the kinetic energy of the particles; which happens when the speed of the particles increases.
A liquid becomes a solid when heat is removed. The energy content decreases, and the speed of the particles decrease.
During evaporation, particles of a liquid gain enough energy to escape from the surface and become vapor or gas. As the liquid evaporates, the average kinetic energy of the remaining particles decreases, leading to cooling of the liquid and its surroundings.
