It will start to melt if the temperature rises above 0 degrees Celsius or 32 degrees Fahrenheit
Officially, the melting temperature of ice is zero degrees Celsius (or 32F). The freezing temperature does vary dependent on the electrolytes added to the water solution. For example, ocean water (salt water), freezes at ~-18 degrees Celsius (or 0F). Various solutions at different concentration of solute offer various degrees of melting/freezing. At 0 degrees Celsius.

and the "boiling temperature".
The numbers depend on the substance and the pressure.

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.
Does the temperature change while a phase chage is occurring?
No, the temperature does not change during a phase change. It remains constant until all the substance has undergone the phase change.
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.
Two factors that are responsible for a phase change?
Change in pressure and change in temperature.
Can molecules change phase and increase temperature at the same time?
Yes, it is possible.
What happens to temperature during a phase change?
Temperature is constant during a phase change.
What do you think will happen to the temperature of a substance during a phase change?
Typically, the temperature doesn't change during a phase change.
Does the temperature of a substance change before the change of state is complete?
No. During a phase change the temperature is constant until the phase change is complete.
How do you get a change of phase?
Change of phase is caused 99% of the time by a change in temperature or pressure.
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.
Why doesn't the temperature change fast during a phase change?
Basically because there is energy needed for the temperature to rise or become lower, but energy is also needed to change the phase, so instead of the energy being used to change the temperature, it is being used to change the phase, therefore temperature does not change.
What A steep slope on a phase-change graph indicates?
Different
Does the temperature change while a phase chage is occurring?
No, the temperature does not change during a phase change. It remains constant until all the substance has undergone the phase change.
Why does phase change occur in materials?
Changing the temperature or pressure of a material we can change the phase.
What happens to a substances temperature during a phase change?
stays the same
What causes a substance to change a phase?
change in temperature
A change of phase takes place at a constant what?
A change of phase takes place at a constant temperature.
