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.

What is The branch of science that deals with the study of matter and how it changes?
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 and changes in what?
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.
Why do phase changes occur and what factors influence the transition of matter between different states?
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 does phase changes occur?
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.
Why does matter undergo changes?
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.
What chemical changes occur during the digestive process?
Cellular respiration
What changes complex molecules into simple molecules?
respiration and microbial degradation of organic matter
The study of matter and changes that occur in matter best describes the science of?
Chemistry
What allows chemical change to occur to matter?
I think its a new substances is made so it changes the matter with it.
How does changes occur in the different changes of matter?
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.
What is always involved when physical or chemical changes occur in matter?
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.
