Yes. This fact is very important in physics. It is known as the conservation of energy.
Energy is conserved in a closed system where there is no net gain or loss of energy. This means that energy can change from one form to another, but the total amount of energy in the system remains constant.
In that case, the total amount of energy is conserved.
The second law of thermodynamics states that energy cannot be changed from one form to another without the loss of usable energy. Enargy is usually lost in the form of heat. This law essentially means that energy changing forms is never 100% efficient.
During a change of state, such as melting or boiling, the particles in a substance rearrange their positions and gain or lose energy to move from one state to another. For example, in melting, solid particles gain enough energy to break their fixed positions and move more freely, turning into a liquid. Conversely, in boiling, liquid particles gain enough energy to break free from each other and turn into a gas.
No, energy conversions always involve a transfer of energy from one form to another. Some energy will always be lost in the form of heat or other forms of energy during the conversion process, due to factors like inefficiencies in the system or resistance.

potential energy
In that case, the total amount of energy is conserved.
A temperature change requires as gain or loss of heat energy.
When particles gain energy, they can move faster and have higher kinetic energy. This increased kinetic energy usually leads to higher temperatures and can cause substances to change from one state to another (e.g., from solid to liquid or gas).
yes, electrons may change energy levels through a gain or loss of energy.

yes it can, if you move the object it will gain kinetic energy
Heat is needed for matter to change form eg: Melting, condensation, etc.
Evaporation is a phase change process in which a liquid turns into a gas. This occurs when molecules at the surface of the liquid gain enough energy to break free and enter the gas phase. Evaporation is a cooling process because it requires energy, which is typically taken from the surrounding environment.
An atoms protons cannot change.The number of neutrons can change (gain or lose) to form an isotope (ex. Hydrogen naturally has no neutrons. But it can gain neutrons to form Heavy Hydrogen, or in other words, a Hydrogen Isotope).An atom can gain or lose electrons to form an ion. Usually an atom will gain or lose electrons to fill its valence (outermost) shell. It takes just as much energy to gain an electron as it is to lose one, so an atom will always look to lose or gain the least amount of electrons possible. (ex. Oxygen has 6 valence electrons. It will look to gain 2 electrons, rather than lose 6).Protons: DO NOT CHANGENeutrons: Can change to form an isotopeElectrons: Can change to form an ion
