The identity of the substance reamain unchanged.
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.
The chemical nature/identity of the substance stays the same when a physical change takes place.
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.
The energy needed to change a substance from a liquid to a gas is called the enthalpy (or heat) of vaporization.
Energy loss is normally associated with a lowering of temperature and is a physical change. However, it can be caused by many other things such as nuclear change or chemical change, both of which are very different from each other and from temperature 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

Yes, the more substance you have, the slower the temperature change.
total thermal energy
Latent heat is the energy required for 1 kg of a substance to change ___________. phase
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.
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.
This is referred to as conservation of energy
Energy transfer and temperature change are directly related. When energy is transferred to a substance, such as through heating, the temperature of the substance increases. The amount of temperature change depends on the amount of energy transferred and the specific heat capacity of the substance.
