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.
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 transitions between different states of matter, such as solid, liquid, or gas. Factors that influence these transitions include temperature, pressure, and the intermolecular forces between particles. When these factors change, the arrangement and movement of particles in the substance can also change, leading to a phase change.
When a solid melts or changes to a liquid. When a liquid boils or changes to a gas. or the reverse when a gas condenses to a liquid or a liquid freezes to a solid. Also it is possible for a solid to go directly to a gas without passing through the liquid stage. This is called sublimation and can occur with sulfur when heated, or ice in the winter when the sun shines on it..
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.

Chemistry
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.
