The discussion of fuel and energy is an important issue in human societies for many years. Due to the limitation of fossil fuels, the use of new energies has been an interest to researchers in recent years. In the meantime, there are things that are considered very simple because of repetition in nature. For example, we know that the volume of water considerably increases during freezing and thereafter a large force creates. This force is so great that sometimes causes to a failure in metallic structures. In this paper, the energy of changing in volume is calculated using thermodynamic relations. This calculation would be a step towards the introduction of this energy. After that a new mechanism for control these forces is discussed. For this purpose, the properties and various states of water at consecutive time steps during the freezing process in conditions of constant pressure and constant volume is calculated. In order to ensure the calculation results, a laboratory model was built and theoretical results were compared with experimental results. As a general result, the changes in volume and water pressure in both states are listed in the charts.
