After chemical reactions new substances are obtained.
Yes, all substances can undergo physical changes. Physical changes do not alter the chemical composition of a substance, but rather change its physical properties such as shape, size, or state (solid, liquid, gas). Examples of physical changes include melting, freezing, boiling, or dissolving.
Some substances have stable chemical structures, making it difficult for them to undergo chemical changes. This can be due to strong bonds holding the atoms together or a lack of reactive sites for other substances to interact with. Additionally, factors such as temperature, pressure, and presence of catalysts can also influence the ease of chemical changes in a substance.
Chemical changes involve the formation of new substances with different chemical properties, while physical changes involve alterations in the appearance or state of matter without changing the chemical composition. Chemical changes typically involve the breaking and forming of chemical bonds, resulting in new substances with different properties. Physical changes, on the other hand, involve changes in physical characteristics such as shape, size, phase, or state of matter without altering the chemical composition of the substance.
Matter can undergo physical changes, such as changes in state (solid, liquid, gas) or shape, without altering its chemical composition. It can also go through chemical changes, resulting in new substances with different properties due to rearrangement of atoms or breaking of chemical bonds. Additionally, matter can experience nuclear changes, like radioactive decay, where the nucleus of an atom changes leading to the formation of different elements.

physical changes
Substances that combine or change to form new substances go through a chemical reaction. In a chemical reaction, bonds between atoms are broken and new bonds are formed. This results in the creation of new substances with different properties than the original substances.
During a chemical change, new substances are always formed as bonds between atoms are broken and reformed. This results in a rearrangement of atoms, causing a change in the chemical properties of the original substances. Energy is often released or absorbed during these reactions.
Reactants are the substances that enter into a chemical reaction to form products. They are the starting materials that undergo chemical changes in a reaction.
Coal is burned to obtain heat; the chemical products of the combustion are carbon dioxide, water and ash.
A chemical change is when substances become new substances that cant go back to its physical properties (the ability to participate in chemical reactions). Chemical changes usually absorb or let off heat. Often, a second chemical change is needed to reverse an initial chemical change.
