As energy is absorbed, the energy moves up to other electron shell levels, but as the energy is released, it goes back to zero (ground state) and the energy is given off as light.

∙ 13y agoIf you are changing from solid to liquid you will gain energy and from liquid to gas you also gain energy but when you are changing from gas to liquid you lose energy and from liquid to gas you also lose energy.

∙ 8y agoAs an example, let's assume that ice melts. The energy of the substance increases. Note that ice at 0 °C is converted into water, also at 0 °C - the increase in energy is potential energy, NOT an increase in temperature, which is related to kinetic energy. This potential energy is related to the force it takes to break the bonds between molecules. The potential energy is again released as heat energy when the water freezes again.

∙ 11y agoIf you are freezing, Energy is taken away from the substance
If you are heating, Energy is added to the substance

What best describe the enthalpy of formation of a substance?
The enthalpy of formation of a substance is the amount of energy that was put in or evolved from the making of that substance from the individual elements.
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 is melting consider because energy is gained by the substance as it changes states?
Melting is a phase change in which a substance changes from the solid state to the liquid state. Changing phases is also a physical change.
What happens when a substance undergoes a physical change?
Physical changes refer to changes of state: solid to liquid or liquid to gas (or vice versa). The chemical structure of the substance does not change, only the amount of energy it contains.
Is energy flow involved in a change in state?
Yes, energy is simply a way for things to change, therefore it is needed. Without energy flow (where energy is either gone or constant) a substance will remain the same.
What happens when a substance change states?
When a substance changes state, Energy within the substance is gained or lost, but the composition is unchanged.
What happens to energy during a change of state why is it a physical change?
Its released or adsorbed. Its "physical" because no new substance(s) is produced.
What happens to energy during a change of state Why is it physical change?
Its released or adsorbed. Its "physical" because no new substance(s) is produced.
When a substance changes state what happens to its thermal energy?
Changes the temperature of the substance
How can the temp of a substance remain the same if it is absorbing energy?
This happens during boiling and freezing the energy being absorbed is going into making the state change.
What happens to the temperatures of a substance while it is changing state?
It can lose or gain energy or it forms the attractions between particles.
A change of state in which energy is removed from a substance is called an?
A change of state where energy is removed from a substance is called an exothermic reaction. This chemical reaction releases energy in the form of light or heat.
How do energy and changes in energy change the state of matter?
When heating a substance the substance's molecules gain kinetic energy, this leads to chemical bonds being broken and thus a change of state.
What best describe the enthalpy of formation of a substance?
The enthalpy of formation of a substance is the amount of energy that was put in or evolved from the making of that substance from the individual elements.
What is the energy needed for a substance to change from a liquid state to a gaseous state?
thermol
How is the thermal energy of a substance related to its 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.
