The situation that you describe, in which heat is being added to or removed from a substance yet the temperature of that substance remains the same, happens when there is a phase change, which can be from solid to liquid, or from liquid to gas, or from gas to liquid, and so forth. This happens because it takes energy to move from solid to liquid to gas, and it produces energy to move in the other direction, from gas to liquid to solid. Molecules or atoms have some degree of attraction for each other, so when they move closer together, or form actual bonds, that is a process that releases potential energy. Moving them farther apart or breaking bonds requires energy.

For example, if you melt ice, you add heat energy, converting ice at zero degrees to water at zero degrees. Breaking the bonds between atoms requires energy - thus, the substance's potential energy increases.

What happens to temperature as solid gold turns to a liquid?
The temperature at which liquid gold solidifies is the same as its melting point, 1064 °C. Generally, the melting point and freezing point for a pure substance are the same. If thermal energy is added to the substance, it will melt. If thermal energy is removed from the substance, it will freeze.
What happens to the thermal energy of a substance during a physical change of state?
it will increase or decrease depending on the states. from solid --> liquid or liquid --> gas it is positive and endothermic, and thermal energy is increasing from liquid --> solid or gas --> liquid it is negative and exothermic, and thermal energy is decreasing
What causes the particles of a substance to lose thermal energy?
The particles in a substance lose thermal energy as the temperature decreases, because the particles are moving and vibrating less.
Has thermal energy been transfered into or out of a substance if the average kinetic energy changes?
Temperature is a measure of the average KE of the PARTICLES of a substance. So if the temperature changes, ave KE changes, thus thermal energy will have been transferred.
Thermal energy added to a substance that is not changing state causes the substances temperature to do what?
To increase.
When heat is added to or removed fron the substance and the temperature remains the the smae where is the thermal energy going?
It is going into melting. The object is so focused on melting it doesn't pay any attention to anything else!
Does temperature have a higher amount of thermal energy in a substance?
The higher of the temperature of a substance, the more thermal energy it has.
What happens to the thermal energy of a substance as its temperature increases?
When a sample of a substance absorbs thermal energy, its temperature rises.
When thermal energy is removed from matter what happens to its temperature'?
it is hot temperature but when thermal energy leaves the temperature is cool
The movement of thermal energy from a substance at one temperature to a substance at a different temperature is called?
heat
Why does a substance's temperature increase when it receives more thermal energy?
Temperature is a measure of the concentration of thermal energy.
How is the themal energy of a substance?
The thermal energy of a substance is measured by its temperature.
What is the movement of thermal energy from a substance at a high temperature to a substance at a lower temperature called?
Heat
What happens to temperature as solid gold turns to a liquid?
The temperature at which liquid gold solidifies is the same as its melting point, 1064 °C. Generally, the melting point and freezing point for a pure substance are the same. If thermal energy is added to the substance, it will melt. If thermal energy is removed from the substance, it will freeze.
When a substance changes state what happens to its thermal energy?
Changes the temperature of the substance
Is degrees related to thermal energy?
The amount of thermal energy a substance has is proportional to its temperature
What is thermal expanison?
Thermal Expansion is the increase in volume of a substance due to an increase in temperature.
