The identity of the substance reamain unchanged.

What effects does an energy change have on the idenitity of a substance?
An energy change does not alter the identity of a substance. It may cause a physical change (like melting or boiling) or a chemical change (like reactions), but the substance itself remains the same at the molecular level. The energy change only affects the arrangement or movement of particles within the substance.
What stays the same in a physical change?
The chemical nature/identity of the substance stays the same when a physical change takes place.
How does the energy of a substance change during an exothermic change?
During an exothermic change, energy is released from the substance in the form of heat to the surroundings. This results in a decrease in the internal energy of the substance, leading to a decrease in its temperature.
What happens to energy during a change of state why is it a phisycal change?
During a change of state, such as melting or boiling, energy is either absorbed or released by a substance without changing its chemical composition. For example, when ice melts into water, it absorbs heat energy, while when water freezes, it releases heat energy. This process is considered a physical change because it affects the form of the substance but not its chemical identity; the molecules remain the same throughout the change.
What is the name of the energy needed to change a substance from a liquid to a gas?
The energy needed to change a substance from a liquid to a gas is called the enthalpy (or heat) of vaporization.

What happens when a pure substance undergoes a chemical change?
when a pure substance undergoes a chemical change it is no longer that same substance. A chemical change changes the identity of the substance. Hope i helped
What is the name of the energy needed to change a substance from a liquid to a gas?
The energy needed to change a substance from a liquid to a gas is called the enthalpy (or heat) of vaporization.
Does the amount of substance change its thermal energy?
Yes, the more substance you have, the slower the temperature change.
Latent heat is the energy required for 1 kg of a substance to change?
Latent heat is the energy required for 1 kg of a substance to change ___________. phase
What change when the amount of a substance change?
total thermal energy
How does thermal energy effect kinetic energy?
Thermal energy is the energy associated with the movement of particles in a substance. When a substance gains thermal energy, its particles move faster, increasing their kinetic energy. This leads to an overall increase in the substance's temperature.
What effect does observing a substance physical property have on the substance?
Physical Properties: The physical properties of a substance are those permanent properties which describe the physical characteristics of the material. Observation where possible, has no effect on the physical characteristic of the material.
Why is latent heat considered potential energy?
This is referred to as conservation of energy
