How can energy be conserved if a substance must gain or lose thermal energy to change state?

Heat is a form of energy. It is just being transferred to the temperature bath (air, water, whatever). It hasn't been destroyed.

The sum of the kinetic and potential energy of the molecules of a substance?
thermal
How does a substance gain heat?
A substance gains heat, or otherwise known as thermal energy, in many different ways. These can be from pressure, friction, the transformation of chemical energy to thermal energy, the transformation of electromagnetic energy to thermal energy, potential energy to the energy of motion (kinetic energy) or a substance can become exothermic during, and after a chemical change if the amount of energy produced from the broken bonds is greater than the amount of energy required for rearranged bonds to be made.
The total kinetic energy of all the particles in a substance is called?
The total kinetic energy of all the particles in a substance is called thermal energy. Thermal energy is measured in joules.
What is the total amount of energy a substance contains?
it is thermal energy
What causes a substance to change its state of matter?
As thermal energy increases or decreases, a substance will change state. This relates to temperature in that the higher the temperature of something, the greater its thermal energy.
What change when the amount of a substance change?
total thermal energy
How is the thermal energy of a substance related to it physical state?
The thermal energy of a substance determines its state, since thermal energy, aka internal energy, is the energy the molecules in the substance have. If the energy exceeds the force holding the substance together the substance undergoes a phase change.The physical state of a substance is related to its temperature, the measure of thermal energy. The substance can change states depending on the temperature, e.g. boiling.

How can the temperature of substance remain the same even if the substance is absorbing thermal energy.?
For example, when ice is melting, the absorbed thermal energy is used to change the phase of the substance - a type of potential energy.
Does the amount of substance change its thermal energy?
Yes, the more substance you have, the slower the temperature change.
How does an increase in total energy of the particles in a substance affect the thermal energy of the substance?
How does an increase in the total energy of the particles in a substance affect the thermal energy of the substance.
What is the principle of conservation of thermal energy?
There is no such principle. Thermal energy can convert to other forms of energy, and vice-versa. The TOTAL energy (thermal + other kinds of energy) is conserved in a close system.
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.
Does thermal energy can cause matter to experience a change of phase why?
Yes because when the thermal energy of a substance increases, it's particles move faster. If the thermal energy of a solid increases, it's particles melts into a liquid. The liquid state of a substance always has a higher thermal energy than it's solid state
How can you add thermal energy to a substance without increasing the temperature?
You can add thermal energy to a substance without increasing its temperature by adding hot water. As the thermal energy of the substance increases, the particles of the substance expands. That is how you can open a bottle by putting it under hot water.
How is the temperature of a substance affected as it undergoes a change of state?
Thermal energy basically is heat. Thermal energy (heat) can change a solid to a liquid state is called melting. The change from a liquid to a solid is freezing. The change from a liquid to a gas is known as vaporization. The opposite of vaporization is condensation. So yeah, thermal energy affects any state of a substance.
