Some laws involved in changes of matter are the Law of Conservation of Matter and the Law of Conservation of Energy. Changes in matter include physical and chemical changes.
In a system, matter and energy can change through processes such as chemical reactions, phase transitions, and electromagnetic interactions. Matter can be transformed into different substances, while energy can be transferred between different forms, such as kinetic, potential, thermal, or electromagnetic energy. These changes occur based on the conservation laws of mass and energy.
When light changes direction after colliding with particles of matter, it undergoes a process known as scattering. Depending on the size of the particles relative to the wavelength of light, different types of scattering such as Rayleigh scattering or Mie scattering can occur, leading to effects like the blue sky or a red sunset.
Light changes direction due to scattering, which can happen when it interacts with particles of matter. This scattering can occur in different ways, such as Rayleigh scattering (predominantly for shorter wavelengths) or Mie scattering (for larger particles). The direction of the light can be altered based on the size and composition of the particles it encounters.
Factors that affect the changes of matter include temperature, pressure, and the presence of catalysts. Changes in these factors can lead to physical changes, such as melting or boiling, as well as chemical changes, such as reactions that form new substances. The composition and properties of the matter can also influence how it changes under different conditions.
Two phase changes that occur when matter loses heat energy are: Solid to liquid: When a substance loses heat energy, it can transition from a solid phase to a liquid phase. This process is called melting. Liquid to gas: Another phase change that can occur when matter loses heat energy is the transition from a liquid phase to a gas phase. This process is known as vaporization or boiling.
It depends on the chemical reaction. For example when you burn something it is a chemical reaction, but that is way different than if you mix baking soda and vinegar which is also a chemical reaction. It changes the matter into a different chemical matter make up of that substance.
Chemistry
I think its a new substances is made so it changes the matter with it.
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 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.

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.
Physical changes occur more often on Earth compared to chemical changes. Physical changes involve alterations in the state or appearance of matter without changing its chemical composition. Examples include changes in shape, size, or state of matter (solid, liquid, gas). Chemical changes involve the formation of new substances with different chemical properties.
Changes of state of matter are physical processes, the molecule remain unchanged.
No, changes in state of matter (such as melting, freezing, boiling) are physical changes, not chemical changes. Chemical changes involve the formation of new substances with different chemical properties.
liquid
There are different processes involved during changes in states of matter. The most common ones include melting, evaporation, condensation and freezing.
