Usually in the form of increased or decreased kinetic energy of the molecules and added or reduced inter-molecular potential energy. Which way it goes depends on the direction of change in state.
During the time of change of state,the heat or temperature is used to increase the potential energy and there by change of state.This time there will be no change in temperature.
If large amounts of heat are transferred to a solid, the solid will likely undergo a phase change and melt into a liquid. This is because the additional heat energy causes the particles in the solid to gain enough kinetic energy to overcome the forces holding them in a solid state.
Energy must always accompany a change in state, whether it is in the form of heat, work, or a combination of both. This energy is necessary to either break the bonds between particles during a phase change involving an increase in energy, or to form bonds between particles during a phase change involving a decrease in energy.
During a state change, such as melting or boiling, the energy being added or removed is being used to break or form intermolecular bonds rather than increase or decrease the kinetic energy of the particles. This leads to a plateau in temperature until the state change is complete.
transition from a disordered arrangement in the liquid state to an ordered arrangement in the solid state, or to a more chaotic arrangement in the gas state. The particles gain or lose energy during this change, leading to alterations in their speed and spacing.

During a phase change, the energy being transferred is primarily in the form of latent heat. This is the energy required to change the state of a substance (such as from solid to liquid or liquid to gas) without changing its temperature.
When there is a change of state, energy is transferred in the form of either heat or work. For example, when a substance changes from a solid to a liquid, energy is absorbed to break the intermolecular forces holding the solid together. Conversely, when a substance changes from a gas to a liquid, energy is released as the substance condenses.
During a change of state, such as melting or boiling, heat energy is absorbed or released without a change in temperature. This heat energy is used to break the intermolecular forces holding the particles together, allowing them to move into a new arrangement. Once the change of state is complete, the temperature resumes changing.
Energy must be transferred for any change of state to occur. A change of state is the same as a change of phase and there are four states that include liquid, solid, plasma, and gas.
The energy which must be transferred to or from a sample of water in order to change it's state is called the Latent Energy or Latent Heat - for example Latent Heat of Evaporation or Latent Heat of Freezing.
a change of state
When work is done on an object, energy is transferred to the object, which can result in a change in the object's state or position. This energy can manifest as kinetic energy (resulting in motion) or potential energy (stored for later use). Work is a measure of the energy transferred to or from an object.
During freezing, energy is transferred from the substance being frozen to its surroundings. As the substance loses heat energy, its temperature decreases until it reaches the freezing point, at which point it transitions from a liquid to a solid state. This transfer of energy continues until the substance is completely frozen.
During the time of change of state,the heat or temperature is used to increase the potential energy and there by change of state.This time there will be no change in temperature.
