How is energy involved in physical change?

During phase changes, energy changes are usually involved. For example, when solid dry ice vaporizes (physical change), carbon dioxide molecules absorb energy. When liquid water becomes ice, energy is released. Remember that all chemical reactions involve a change in the bonds of the reactants.

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.
