Eating food gives your body energy by changing it from tried and exhausted to full of energy. You need energy to have electricity so you can do homework and games.

Well, the most common ones would be solid to liquid; solid to gas; liquid to gas. Of course, any other valid change between the 15 or so different states of matter involve an energy absorption in one direction, and an energy emission in the opposite direction.
Energy is absorbed during melting, boiling and sublimation.
Please note that a "change of state" involves TWO states, not just one. Using just the three most common states of matter: * A solid can change to a gas * A liquid can change to a gas * A gas can change to a liquid * A gas can change to a solid * A solid can change to a liquid * A liquid can change to a solid The first four changes in the list above involve gases.
yes because three times of energy transform

Temperature change. The fourth class of reactions is much more difficult to detect than the previous three. This fourth class is really the basis of the other three. Every chemical reaction involves energy in some form, because all chemical reactions involve the breaking of old bonds, the forming of new bonds, or both. We know that every chemical bond contains energy, or it would not exist. This result means that every chemical reaction involves an energy change because the bonds are changed. Energy tied up in the bonds of atoms, molecules, ions, and the rest of the chemical system is called enthalpy. The absolute amount of this energy cannot be measured, but the change in enthalpy from the reactants to products can be measured. If the energy is lost (given off), the reaction is exothermic; if energy is gained, the reaction is endothermic
