Changes in matter are defined as all the physical, chemical and energetic changes of matter.
Corps
Some changes take place naturally but, through their interactions with their environment, humans are also responsible for many of the changes that occur around them and even in their own bodies. Physical and chemical changes necessarily involve a transfer and transformation of energy. However, during these transformations, the mass of matter is always preserved as well as the number of atoms of each element composing it.
