A Physical change -to you unlucky study islander
A liquid can expand when thermal energy is absorbed which is known as thermal expansion, but the thermal energy is not enough to change the liquid's state. When there is enough thermal energy, the liquid may change to a gas if the particles move fast enough to escape the liquid or it may change to a solid if the thermal energy is released from the matter.
move faster and break free from other particles, entering the gas state.
The thermal energy from heat causes the particles of the liquid to vibrate more (increasing their kinetic energy), then the vibrating particles get enough kinetic energy and are vibrating enough to allow then to break any sort of bonds (most likely ionic) that they have with surrounding particles and, as they become less dense, the liquid evaporate and becomes a gas.

A Physical change -to you unlucky study islander
Heat energy is a measure of how fast particles of matter are vibrating. As more energy goes into the matter, the particles vibrate faster. At some point (it is different for each material) the particles move fast enough to change phase. When water boils, the particles change state from liquid to gas.

The particles themselves don't change, but their behavior does. If you are simply heating a solid, but not to the point of a phase change, the particles remain locked in place but they vibrate faster. If you heat a solid to the point that it goes through a phase change, the particles start to vibrate fast enough to break the intermolecular bonds and keep them broken enough to allow the particles to slide past and around one another.
If enough is concentrated matter can be created from energy.
The energy of the particles differ because in solids the particles vibrate in a fixed position and remain close.Giving a solid definite shape and volume.While the particles of liquid are moving faster,letting them have enough energy to slide past one and another.This allows liquid to take a shape of it's container. The particles of a gas move so quickly that they have enough energy to move freely away from other particles.These particles take up as much space as possible and spread out to fit any container.

the particles in a gas lose enough thermal energy to form a liquid.
As cells gain energy (usually heat) they move faster. When particles get heated enough, they will change state. Example: boiling water results in water vapour.
