Why does the temperature remain constant during changes of state?

Temperature:
The quality of matter known as temperature reflects the amount of energy that propels its individual particles. It is a gauge of how warm or cool a material is in relation to another. The coldest theoretical temperature is absolute zero.Reason for constant temperature during change of state :
Because the heat energy necessary to change the state of matter is used to break the intermolecular interactions and other attraction forces, the temperature is set during the change of state.The temperature stays constant because the heat supplied is sufficient to raise the substance's temperature and exhausts itself by changing the substance's state of matter.As a result, the temperature remains constant since all of the heat is used and no external releases heat or absorb it.In short, heat is utilized in latent heat conversion.Latent heat:
Latent heat is described as heat or energy absorbed or released during a substance's phase shift.It could be from a gas to a liquid or from a liquid to a solid and vice versa. Enthalpy is a heat characteristic linked to latent heat.The temperature of any substance remains constant throughout a state shift since the heat energy produced is used up in changing the state of matter and also for breaking numerous bonds or attractive forces.
