That depends entirely on the substance in question, but it is called the specific heat capacity.
Energy = specific heat capacity x mass x change in temperature (Celsius or Kelvin)
q = Cg x m x (T2 - T1)

Why does temperature stay the same during a phase change?
The temperature, in Physics, means the measure of Kinetic Energy in a substance. When a substance is either heated or cooled, Kinetic Energy is either being added to taken away from the substance. When the amount of KE in the substance changes, the temperature change. However, when the substance is changing its state, because all the KE change in the substance is being used up to change the state, the temperature will not change. When the substance is changing state, the KE can be measured by calculating the heat of fusion and heat of vaporization.
When energy enters a substance what is it called?
The electrons of different atoms start moving due to the change in kinetic energy. This produces a rise in the temperature of the substance. Each substance will have different reactions to the temperature changes{THIS WAS NOT MY ANSWER}
Why may the temperature of a substance change when energy is added?
Thermal energy of a substance is determined by the movement of the molecules and the potential energy of the arrangement of molecules. Heat transfer will stop when thermal equilibrium is reached. It depends upon the substance how long that takes.
What is the amount of energy needed to change the temp of a substance called?
The specific heat is the amount of heat per unit mass required to raise the temperature by one degree Celsius
What is the relationship between energy and temperature change?
When heat is transferred in a space the average energy of the particles - the temperature of the substance - is affected, by increasing or decreasing. The change in temperature depends on the number of particles affected.
What is the amount of change in the thermal energy of a certain mass of a substance per degree of change in temperature?
That is called the specific heat.
What is specific heat capacity?
Is the amount of energy that is required to change the temperature of 1kg of a substance by 1 degree Celsius with no state change.
What is the amount of change in the thermal energy of a certain mass of a substance per degree of cahange in temperature?
That is called the specific heat.
How does a substance 's temperature change when the average kinetic energy of it's particle increases?
As the average kinetic energy of a substance increases, the temperature will increase.
Does the energy content of a substance change during a phase change?
Yes, but not the temperature.
How is the temperature of a substance related to the energy of a movement of the particles in a substance?
It is hard to exactly define temperature in terms of such things - but roughly speaking, the temperature is the average kinetic energy (energy of movement) per particle, per degree of freedom.
How is the temperature of a substance related to the energy of movement of the particles of a substance?
It is hard to exactly define temperature in terms of such things - but roughly speaking, the temperature is the average kinetic energy (energy of movement) per particle, per degree of freedom.

Is temperature change chemical?
No. Temperature is not a change of any sort. It is a measure of the average kinetic energy of the particles in a substance.
Is temperature a form of energy?
Temperature is not a form of energy, but a measurement of energy (specifically, heat energy). You can't add temperature to a substance, because every substance already has a temperature, whether it be at -50o C or 900o C. However, you can add heat to change the temperature.
What term is used to describe the amount of energy it takes for a certain amount of substance to be raised one degree in temperature?
A substance's specific heat capacity (C) is the amount of heat energy required to raise the temperature of 1g of a substance 1 degree celsius.
