It takes energy to alter temperature, and it also takes energy to change state, at least in the direction of more energetic states, which is to say, to melt a solid or to vaporize a liquid. If energy is being consumed by the change of state itself, then there is no energy available to change the temperature. So the temperature remains constant. In practice, this means for example that things boil at the boiling point. Boiling water is always exactly 100o Celsius. It can get no hotter until it is all boiled. The steam, of course, can then get hotter.

What happens to a temperature of a substance while a changing of state occurs?
As a substance changes state, the temperature remains constant.
When the physical state of a substance changes during a phase what happens to the temperature of the system?
The temperature remain constant during a change of phase.
Does the temperature of a substance changes before the change of state is completed?
No. During a phase change the temperature is constant until the phase change is complete.
What are the temperature changes that occur in ice as energy is added starting at the frozen state and ending in the vapor state?
As energy is added to ice starting from the frozen state, the temperature of the ice initially remains constant at 0°C until it melts into water. Once it becomes liquid, the temperature of the water rises until it reaches 100°C. At this boiling point, the water again stays at a constant temperature while it converts into steam. Finally, as energy continues to be added, the steam's temperature increases beyond 100°C.
Why does the temperature remain constant at the transition temperature even though heating is continued?
At the transition temperature, the heat goes into causing the change in state. Once the change in state is complete, the temperature will change.

Does the temperature of a substance changes before the change of state is completed?
No. During a phase change the temperature is constant until the phase change is complete.
What Happens to the temperature when a chemical changes state?
It remains constant, since all the energy goes into changing the intermolecular bonds.
True or false the temperature of a substance changes during a change in state?
False. The temperature of a substance remains constant during a change in state until all of the substance has completed the phase change.

Hawaii is tropical and has the most constant temperature.

What would happen to the water vapour in a completely sealed tank?
In a completely sealed tank, the water vapor would reach a state of equilibrium where the rate of evaporation equals the rate of condensation. As the temperature and pressure stabilize, the vapor might form a mixture of gas and liquid water depending on the temperature and the tank's volume. Over time, if the temperature remains constant, any additional changes in pressure could lead to changes in the state of the water vapor, but overall, the system would maintain a constant amount of water in vapor and liquid forms.
What is unsteady state of heat transfer?
Unsteady state heat transfer occurs when the temperature of an object changes with time, indicating that the system is not in thermal equilibrium. This can happen during the initial warm-up or cool-down of a system, or when there are sudden changes in external conditions affecting heat transfer. The rate of heat transfer during unsteady state conditions is not constant and varies with time.
What happenes to the temperature of a material when it changes state?
When a material changes state, its temperature remains constant until the entire phase transition is complete. For example, when ice melts into water, the temperature stays at 0 degrees Celsius until all the ice has turned into water. Conversely, when water vapor condenses into liquid water, the temperature remains constant until all the vapor has transformed into liquid.
What usually happens in general for a gas at a constant volume?
The gas volume become constant when the pressure is increased to a point that makes the distance between the gas molecules equal to zero at this point no more increase of temperature with pressure is observed. Or if the pressure and temperature are kept constant within a system then the volume can also be constant as long as you are able to maintain the pressure and temperature at constant level.
