Temperature and pressure are two factors that can cause a phase change in a substance. A substance will change from one phase to another when its temperature or pressure surpass a certain threshold, known as the melting point, boiling point, or sublimation point.
it changes depending upon the temperature
A substance change from a solid to a liquid at its boiling point. This is when it reaches a certain temperature.
Changes of state happen at a constant temperature because the heat energy being supplied is used to break or form intermolecular forces rather than increase the temperature of the substance. This process involves a change in the arrangement of molecules rather than an increase in their kinetic energy, resulting in a constant temperature until the change of state is complete.
The boiling temperature of an element can change by changing the pressure.
Yes, a material can gain energy without changing temperature through a process called phase change, where the energy is used to change the state of the material (solid, liquid, gas) rather than increase its temperature. Examples include melting ice or boiling water.
Melting is a phase change where solid becomes a liquid. The latent heat of fusion must be supplied to produce phase change from solid to liquid. About 144 Btu must be supplied to change 1.000 pound of ice at 32 degrees F to 1.000 pound of liquid water at 32 degrees F. Boiling is a phase change where a liquid becomes a vapor. The latent heat of vaporization must be supplied to change a boiling liquid to a vapor. For water boiling at 14.7 psia ,970.3 Btu of heat must be supplied to change 1.000 pound of boiling liquid water to vapor.
During the process of melting and boiling, the heat energy supplied is being used to break the intermolecular forces holding the substance together. This energy is known as latent heat and does not result in a temperature increase because it is being used to change the state of the substance rather than raise its temperature. Once all the substance has melted or boiled, any additional heat energy supplied will then raise the temperature.

At the boiling point the temperature remain unchanged.
In this first heat boil the water at its boiling point that is 100 degree Celsius, when the temperature is reached then heat supplied to water not boils the water it is used to change the state of the matter means heat is used to overcome the forces of attraction to change its state and the heat is latent heat of vaporisation.so this is latent heat (hidden heat) which not increase the temperature for some time.

Because that is the hottest temperature it can get.
