A change is said to be physical if no new substances are formed. Physical changes are temporary and can easily be reversed to give back the substances in their previous form. Freezing of water is an example of a physical change.
A change is said to be chemical if new substances with different properties are formed. Chemical changes are permanent and cannot be reversed to give back the substances in their previous form. Burning of paper is an example of a chemical change.
During respiration, the body takes in oxygen and releases carbon dioxide through a series of chemical reactions. Oxygen is used in the process of breaking down glucose to produce energy in the form of ATP. As glucose is broken down, it is converted into carbon dioxide and water, which are then released as waste products.
The branch of science that deals with the study of matter and how it changes is called chemistry. Chemistry examines the composition, structure, properties, and reactions of matter to understand various physical and chemical changes that occur.
Chemistry is primarily concerned with the composition of matter and the changes that occur in that matter. It focuses on understanding the structure of atoms, molecules, and how they interact to form new substances through chemical reactions.
Phase changes occur when a substance changes from one state of matter to another, such as when a solid melts into a liquid or a liquid vaporizes into a gas. This usually happens when the substance's temperature or pressure is altered.
Matter undergoes changes due to interactions between its particles, such as collisions, chemical reactions, or changes in temperature, pressure, or energy levels. These interactions can cause rearrangement of the particles or changes in their properties, leading to physical or chemical changes in the matter.
A person who studies changes in matter is called a chemist. Chemists investigate how matter changes at the molecular level, including processes like chemical reactions and phase changes. They use principles of chemistry to understand, analyze, and manipulate matter.

I think its a new substances is made so it changes the matter with it.
Changes in the states of matter occur through processes like melting, freezing, condensation, vaporization, and sublimation. These changes involve the rearrangement of particles at the molecular level due to changes in temperature or pressure. During these transitions, energy is either absorbed or released.
When physical changes occur in matter, the substance's state or appearance changes without altering its chemical composition. In contrast, chemical changes involve a modification in the substance's chemical composition, resulting in the formation of new substances.
