Can all substances go through physical changes?

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.


What 2 things can chemical and physical change go through?

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.

What are the changes that matter undergoes?

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.

When rocks go through the rock cycle do they experience physical and chemical changes?

Yes, rocks in the rock cycle can undergo both physical and chemical changes. Physical changes involve processes like weathering, erosion, and pressure, which can break down rocks into smaller pieces or change their shape without altering their composition. Chemical changes involve processes like melting, crystallization, and metamorphism, which can alter the mineral composition of rocks through reactions with fluids or heat and pressure.


Why can't some substances not go through chemical changes easily?

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.

How does temperature affects chemical changes?

Chemical changes generally go more quickly when the temperature increases, and conversely more slowly when it decreases.
