Melting, evaporation, and sublimation are changes of state that absorb thermal energy. During these processes, the particles in a substance gain energy to break intermolecular bonds and overcome attractive forces between them, resulting in an absorption of thermal energy.
Freezing is the process by which a substance changes from a liquid state to a solid state by removing thermal energy. This removal of thermal energy causes the particles in the substance to slow down and come closer together, forming a solid structure.
When matter changes state, thermal energy is either absorbed or released. For example, when a solid melts to become a liquid, thermal energy is added to break the bonds holding the solid structure together. On the other hand, when a gas condenses to become a liquid, thermal energy is released as the gas molecules slow down and come closer together.
Thermal energy increases the kinetic energy of the particles within matter, causing them to vibrate and move faster. This in turn leads to an increase in temperature and can cause changes in state (e.g. melting, boiling).
When a liquid changes to a solid, thermal energy is released from the substance. This energy is used for the particles to slow down and become more ordered into a solid state. The release of thermal energy is known as heat of fusion.
When a substance gains thermal energy, its temperature increases as the particles within the substance move faster and have greater kinetic energy. This increased thermal energy can lead to changes in the physical state of the substance, such as melting or boiling if enough energy is absorbed.

a change of state
When water has heat and energy it changes energy. The energy that it changes to is called thermal.

A. Melting is the change of state that releases thermal energy. When a substance melts, it absorbs thermal energy from its surroundings to overcome the intermolecular forces holding its particles together.
The thermal energy of a substance increases when it changes from a solid state to a liquid state, or from a liquid state to a gas state. This is because the molecules in the substance gain more kinetic energy and move more freely as the substance transitions between states of matter.
10g of bromine will store the most thermal energy in its liquid state, as this is when bromine has the highest specific heat capacity. In its liquid state, bromine can absorb the most thermal energy per gram compared to its solid or gas states.
When thermal energy is added or removed, the state of matter changes to another eg. solid becomes liquid and liquid becomes gas.
